Prince William and Duchess Catherine are "cool dudes".
Youngsters who met the royals at an activity centre in Adelaide, Australia, today (23.04.14) were so impressed they described them as a "couple of cool dudes".
The royals were treated to a series of BMX bike tricks by some of the youth and William, 31, was even handed a spray can to create his own graffiti art on a nearby wall.
Simon Burt, leader of the Aerosol Angels, said: "He did a pretty good job. And he admitted when he'd finished his bit of art work that he was now addicted."
Another painter said: "He paints very well. He filled in part of the blue sky and didn't go over any of the lines."
The royals then witnessed an exhilarating BMX show which featured mid-air twists, somersaults and more.
18-year-old rider Liam Zammit is quoted by the Daily Express newspaper as saying: "Yeah, we all agreed [they were cool] because they showed such an interest in what we were doing.
"The Duchess noticed I had a scar on my leg and asked if I had done it today but I said it was from practicing.
"I think we put on a good show for them, that's for sure."

Lily Allen asks for the pop crown in the video for her new track 'Sheezus'.
The 'Hard Out Here' singer, who is about to release her new album 'Sheezus' after a four-year hiatus, appears in the new promo for the title track under a blue light, wearing a hoodie and gold chain with glowing eyes, as she sings about wanting to be number one in the pop world.
In the video, she gives a shout out to her fellow female pop stars, including Lorde, Rihanna and Beyonce, singing: "Riri isn't scared of Katy Perry's roaring/ Queen Bey's gone back to the drawing/Lorde smells blood, yeah/ She's about to slay you/ Kid ain't one to f**k with when she's only on her debut."
Lily adds: "Second best will never cut it for the divas/ Give me that crown b**ch/ I wanna be Sheezus."
She also describes Gaga as a "martyr" and talks about the difficulties of staying ahead of the rest in the music industry, singing: "I'll take the hits, with the punches/ I'll get back up/ It's not as if I've never done this/ Then again, the game is changing/ Can't just come back jump on the mic and do the same thing."
Lily adds: "Wish me luck/ I'm gonna need it/ I'll see you on the other side if I'm still breathing."
Lily's new album 'Sheezus' is out on May 5 via Regal Recordings.

'EastEnders' star Hetti Bywater almost had a panic attack filming scenes as a dead body.
The Lucy Beale actress - who was killed off last week - admits she struggled to keep still while filming scenes in which her on-screen father, Ian (Adam Woodyatt), identified her body.
Speaking about the dramatic moment, which aired last night (22.04.14), Hetti said: "When I get revealed through the curtains, they told me, 'The first time that Adam sees you is the first and only take that we're going to do'. So I panicked.
"I went into almost like a panic attack because during the filming, when they said action, my eyes were quivering and I couldn't stop them, it was uncontrollable. And my palms were sweating. I was like, 'Oh my gosh, I'm literally mucking up the scene so much and they didn't do another take!' "
Lucy's murder will launch a new 'whodunit?' plot that will culminate next year to mark the 30th anniversary of the BBC One soap.
Executive producer Dominic Treadwell-Collins devised the storyline when he joined the show last year and says he chose the Beales because he wanted them at the forefront of the anniversary.
In an interview with the official 'EastEnders' website, he said: "The Beales are the first 'EastEnders' family ... so for me, building up to the 30th anniversary of the show next year, I wanted a big, epic story that put the Beales at the centre of the show and put Ian - the show's only original character - at the centre of the show."

Susanna Reid will earn £400,000 for 'Good Morning Britain'.
The 43-year-old TV star, who quit her role fronting 'BBC Breakfast' to become the new face of ITV breakfast, is to earn less than half the £1 million salary she was rumoured to be receiving for her jump to the channel.
However, Susanna will still earn double her BBC fee, which is thought to be £200,000.
A source told The Sun newspaper: "The idea that Susanna is getting a £1million salary is ludicrous. She was working at the BBC where they weren't paying her anything like that.
"Her deal is less than half of £1million but still a significant improvement on her BBC earnings. This is a cut-price deal when compared to others."
ITV bosses refrained from handing Susanna a million-pound deal similar to Adrian Chiles and Christine Bleakley, who jumped ship from BBC to ITV in 2010, but failed to improve the fortunes of ITV's breakfast slot when they hosted 'Daybreak'.
The insider added: "Adrian and Christine were an expensive experiment. The bosses have tired of handing over footballer-style wages."
Susanna will begin her new role with ITV next week when 'Good Morning Britain' replaces 'Daybreak'.

Jimi Mistry says his wife Flavia Cacae puts him to "shame" in the gym.
The 'Coronation Street' star claims his professional dancer wife - who he met during his appearance on 'Strictly Come Dancing' in 2010 - often puts him through a series of gruelling workout routines in order to help him bulk up for his role as gym boss Kal Nazir in the ITV soap.
Jimi, 41, told The Sun newspaper: "She puts me to shame. We go training together when we can. She cracks the whip a bit but I do it to her too. We went to the gym last weekend and I put her through her paces. You've got to believe what you're playing!"
Meanwhile, Jimi claims his recent love triangle in 'Corrie' is set to cause tension on the cobbles, as Leanne Tilsley (Jane Danson) will finally come clean to her estranged husband Nick (Ben Price) that she has feelings for Kal.
He explains: "As well as Nick, there's going to be the issue of what Kal's family think of Leanne and how she fits in with them. There's already friction between Kal and his dad.
"Also, what does Nick's mum Gail think? She'll have something to say, won't she?
"Then my mum is coming in. There are going to be some strong personalities. And there are cultural differences, so it's not going to be straightforward."

Peter Capaldi's character has been killed off in 'The Musketeers'.
The actor's time-consuming new role as the titular Time Lord in 'Doctor Who' has meant his Cardinal Richelieu character has had to be axed from the BBC One period drama, with Marc Warren replacing him as a brand new villain.
Since writers were unaware of Peter's high-profile new job at the time of filming the first series of 'The Musketeers', the Cardinal wasn't given a proper send-off during his final episode.
Tom Burke, who stars as Athos, told Radio Times magazine: "Come the next series, the Cardinal will be dead. He'll just be gone.
"We're all like, 'Where's the Cardinal? Oh he's dead.' It's a great example of economic storytelling. Their new nemesis will be Rochefort, who's played by Marc Warren."
It was recently confirmed that 'Mad Dogs' star Marc had joined the cast as the Comte De Rochefort, a "dashing and persuasive aristocrat with a talent for sword fighting and a taste for adventure", but Cardinal Richelieu's fate was unknown at the time.
Filming for the second series has already begun in Prague, and Tom's fellow Musketeers Luke Pasqualino, Howard Charles and Santiago Cabrera are all returning to the programme.

Meryl Streep "hates" inviting people to awards ceremonies.
The 64-year-old actress - who has been nominated for an Oscar 18 times and won three of the coveted statuettes - picked up the 14th annual Monte Cristo Award by the Eugene O'Neill Theater Center for her "artistic commitment to excellence and accomplishment" in the arts in New York on Monday (21.04.14), and though he was there to support her, her husband Don Gummer insisted he no longer gets "excited" when his wife wins a prize.
Asked if he gets sick of watching her pick up honours, Don told the New York Daily News newspaper's Confidenti@l column: "Not sick, I just don't get excited. She just always hates asking people or having people asked to come support her. She gets tired of it ... after a while what can they say."
Don also admitted he and his wife - who have been married for 37 years and have children Henry Wolfe, 34; Mamie, 30; Grace, 27; and Louisa, 22, together - squabble over household chores, and a regular argument between them is whether to "wash the dishes or put them in the dishwasher."
Meryl was presented with the accolade by actor Joe Grifasi, who told the audience - which included Catherine Zeta-Jones and Michael Douglas - about a time he and the actress went to a beach several years ago.
They swam out to a rock and she told him she wanted to be married with children by the time she was 35.
And in her acceptance speech, Meryl also recalled the incident, saying: "Thank you to my husband for my four children that I dreamed up on that rock on the beach that day. He came along thank God."
And the 'Devil Wears Prada' star also received a comical musical tribute from songwriting duo Robert Lopez and Kristen Anderson-Lopez, who reworked 'Love is an Open Door' from 'Frozen' to be about Meryl.
A source said: "It was about how much they love Meryl and her movies and the chorus was, 'We want to be Meryl Streep.' At the end, they sort of whispered Meryl f***ing Streep, which was very funny."

Katy Perry made children cry after gatecrashing a five year old's birthday party.
The 'Dark Horse' hitmaker dressed up as a clown for the video for her track 'Birthday' and carried out a prank at a party, where she attacked a man with a piñata stick and staged a car accident, but the spoof incident left children in tears.
Eye witnesses told TMZ, Katy pranked a real birthday party and most of the guests had no idea it was a joke.
Children were crying and one woman "stormed away" visibly upset by her antics.
The hidden camera gag was shot at Knollwood Country Club outside Los Angeles and a video obtained by the website shows one little girl saying, "Mommy, I want to leave."
During an interview on 'Jimmy Kimmel Live', Katy spoke about going "undercover" at the bash, but didn't mention the fall out.
Speaking earlier this week, she said: "I just did a music video completely undercover as five of the world's worst birthday entertainers, because I was sick of making gorgeous music videos where I'm sexual."
Jimmy joked: "People are sick of that, yeah, really tired of looking at you."
Katy, 29, then previewed a clip of the video which sees her dressed as a clown drinking and burping, saying: "I'm not really a birthday party entertainer, I'm just trying to get some cash on the side," adding, "Happy birthday kids."

Gwyneth Paltrow has been given a temporary restraining order against an alleged stalker.
The 'Iron Man' actress has taken legal measures against Nickolaos Gavrilis, ordering him to remain at least 100 yards from her, her estranged husband Chris Martin and their two children, Apple and Moses.
The super fan is accused of trying to sneak into their family homes in London and Los Angeles, according to ET Canada.
The court petition granted last Friday (18.04.14) featured details of the incidents from Terry Abbott, Gwyneth's Director of Security.
The first attempted break-in allegedly occurred in September 2012, when Nickolaos tried to get into the GOOP mogul's house by saying he had a business meeting with her.
Legal action was taken when the supposed stalker "made a third attempt" to access Gwyneth's residence in Los Angeles, California, earlier this month.
He was also spotted on April 10 near the Tracy Anderson Studio, the actress' regular fitness haunt.
The man has also been accused of posting "disturbing" messages on Gwyneth's Facebook page, causing her "substantial emotional distress".
Dr. David Glaser, a clinical and forensic psychiatry specialist, backed up the claims, saying the man poses a "danger of great and irreparable harm to Ms. Paltrow, her family, and those close to them."
A hearing will take place on May 12 to decide whether the restraining order should be made permanent.

Leslie Mann regrets using her marriage as inspiration for 'This Is 40'.
The 'Other Woman' star admits she became "annoyed" by the "invasive" questions about her relationship with director Judd Apatow when she starred alongside Paul Rudd in her husband's 2012 romantic comedy, because people failed to understand that aspects had been "exaggerated" for entertainment value.
Leslie, 42, told Stylist magazine: "The thing that bothered me, and I always tell Judd this, a lot of it is based on our lives but some of it is based on our friends' lives or whatever. I mean, we decided to put it out there, it's our own fault, but I did feel it was a little invasive at times. I kept getting annoyed because it was like, 'Argh! Everyone's in my business!"
Leslie - who has daughters Maude and Iris with Judd - insists it has always been her own choice to put her career on hold in order to raise her children and she often feels "incredibly guilty" when she has to leave them to shoot her next film.
She explained: "I have put stuff on hold - little bits here and there. There were times I chose to raise my kids, to be with them. And Judd makes more money than me so it makes sense. Even now they're 11 and 16, I feel incredibly guilty being away from them. I miss them so much. It's hard because when I'm with them every single day and night and they're like 'Do this! Get me that! Drive me here!' I'm like 'Argh! I wish I could be off working!' But I try to find the balance, even though it's impossible."

Laura Prepon thinks Tom Cruise is "hot".
The 'Orange is the New Black' actress insists rumours she is dating the 'Mission: Impossible' star are untrue, but she is "flattered" by the speculation, even though she finds it funny.
She told website The Daily Beast: "I'm flattered because I think he's hot, so I'm like, 'Oh, that's nice,' and apparently he's very gentlemanly with me.
"Apparently we get along great and he knows that I have a favourite bottle of wine that I didn't even know I had."
The 34-year-old star finds some of the claims about her personal life "unbelievable" and she is baffled by the level of fictitious detail given about her supposed relationship with the 51-year-old actor.
Speaking to Sheknows.com, she said: "Apparently I'm dating Tom Cruise right now. And apparently he doesn't want me doing the show because I portray a lesbian and I'm a Scientologist. This is false. Where are they even getting this stuff? It's unbelievable to me."
It had previously been claimed Tom and Laura first went on a date at the Manor Hotel in Los Angeles last November and the actor - who was previously married to Mimi Rogers, Nicole Kidman and Katie Holmes - was instantly smitten.
A source previously said: "They spent three hours laughing and joking. It's clear Tom is smitten and after the date he was on cloud nine.
"They had their second date at the restaurant too, meeting for Sunday Brunch and she then accompanied him a few days later to a dinner party at John [Travolta] and Kelly's [Preston] home."
Laura previously dated 'Malcolm in the Middle' actor Chris Masterson before their reported split in 2012.

Quentin Tarantino's lawsuit against Gawker has been dismissed.
The award-winning director was furious when the website posted a link to a leaked copy of his 'Hateful Eight' script, forcing him to scrap plans for the Western, but the site maintains there is no case and says directing people to an online version of the script was fair use as it hadn't "reproduced" the material.
A federal judge in California has granted the website's motion to dismiss the director's copyright infringement lawsuit since Tarantino failed to display particular details regarding the infringement facilitated by Gawker's actions.
However, the filmmaker can re-file the case if he makes key changes.
In an order obtained by Deadline.com - titled 'Quentin Tarantino -v- Gawker Media' - Judge John Walter said: "The Court grants Defendant's Motion on the grounds that Plaintiff has failed to adequately plead facts establishing direct infringement by a third party or facts that would demonstrate Defendant either caused, induced, or materially contributed to the alleged direct infringement of those third party infringers.
"Plaintiff merely speculates that some direct infringement must have taken place.
"For example, Plaintiff's Complaint fails to allege the identity of a single third-party infringer, the date, the time, or the details of a single instance of third-party infringement, or, more importantly, how Defendant allegedly caused, induced, or materially contributed to the infringement by those third parties."
Tarantino claims he only gave the script for 'The Hateful Eight' to six people and believes one of them must have let their agent see it, who subsequently sent it on.
