George Clooney has arrived at his wedding by speedboat.
The 53-year-old actor - who is set to marry human rights lawyer Amal Alamuddin, 36, this evening (27.09.14) - waved to onlookers as he jetted to the seven-star Aman Hotel in Venice, Italy, at the back of a flotilla of water taxis crammed with a host of celebrity guests.

Although his bride was absent from the procession, George was also accompanied by Amal's parents Ramzi and Baria, his father Nick and his mother Nina.
According to the New York Post newspaper's Page Six column, the star was in high spirits as he headed to the destination even shouting to a member of the crowd when they asked if his wedding was "really happening?"
He replied: "Yeah, right now!"
It is thought tonight's nuptials will be the first of two ceremonies with another civil ceremony taking place in the city on Monday.

She wrote on her Twitter account, along with a poignant quote about motherhood: "Absolutely love being a mother to two kids! Haven't gotten a wink of sleep taking care of & staring at my daughter (sic).

The 31-year-old actress - who is set to welcome her baby daughter with her partner Ashton Kutcher - is tired of waiting for her to arrive and "just wants the baby to come out already".
The 'Black Swan' star has kept busy by remaining active in the months up to her due date - attending prenatal yoga classes, going for walks and spending quality time with Ashton, 36 - but is now said to be getting desperate to go into labour.
A source close to the star told People.com: "Mila just wants the baby to come out already!
"Mila hasn't slowed down at all. She seems to have a lot of energy."
The couple were also left disappointed this week after Mila didn't go into labour while Ashton was on a break from filming 'Two and a Half Men'.

Ashton alluded to his pre-baby jitters on Twitter on Thursday (18.09.14), writing: "Nervous is excited's victim sister."

Vitalii Sediuk had to be "cautious" with his latest prank on Kim Kardashian.
The Ukranian-born media personality, 25 - who tackled Kim, 33, as she arrived at the Balmain SS15 show at Paris Fashion Week earlier this week - has confessed he had to take more care when pulling off the stunt because she is a woman.
However, the Hollywood Prankster - who has previously accosted stars including Bradley Cooper, Leonardo DiCaprio, Brad Pitt, America Ferrera and Will Smith at red carpet events - confessed he would have pulled out all the stops if he had been ambushing Kim's husband, Kanye West, instead.
He told The Hollywood Reporter: "I had a feeling that Kim would show up there because she is friends with the designer of Balmain. I basically came there just for them. I knew they were going to be the biggest guest of the night.
"If it was Kanye West, I would have done it like I did it with Bradley Cooper and Leonardo DiCaprio.
"But with Kim Kardashian, I was very cautious because I know she is a woman -- so I kind of hugged her legs. I already had a bad experience with America Ferrara. It's different with men."
Vitalii - a former journalist - insisted he is just "a normal guy" and doesn't mean to offend anyone with his antics.
He explained: "I like the show business world. But it's obviously not my intention to offend someone. It looks like I'm a monster, but I'm a normal guy. Well, what I'm doing isn't normal -- but I don't have bad intentions."
He added: "I'm already banned in America. I could be banned in the European Union next. I hope I will not be."

Chloe Grace Moretz "begged" to audition for 'The Equalizer'.
The 17-year-old actress - who stars alongside Denzel Washington in the action thriller film - has revealed the part she landed was originally written for a 24-year-old.
Speaking on 'Good Morning America', she said: "I kind of begged to audition for it and I met with Antoine [Fuqua; the director] and we had a great meeting.
"And then I auditioned with Denzel and it went really well. It worked right."
The 'Kick Ass' star - who plays a Russian prostitute in the film - admitted she struggled to learn the language required by the part.
She explained: "I kind of had a cheat sheet on my phone all the time - I had it written down in phonetics.
"It's a hard language to learn because it's so different to English."
Meanwhile, Chloe - who has starred in numerous box office hits - has revealed that she has had to fight for every role she gets because of her age and gender.
She explained: "I'm still fighting hard for every role I get. I'm still fighting the boundary of how old or young I can be, or how they want me to be something I'm not.
"You are always having this struggle, especially as a female actor against the higher powers trying to keep you in a spot which makes them feel comfortable. That's a major thing I'm battling right now."

Kate Bosworth wants to clear her schedule to start a family.
The 31-year-old actress, who married director Michael Polish last year, has reportedly been telling her agents that she doesn't want to take on any more roles in the near future as she wants to focus on getting pregnant.
A source told America's OK! magazine: "Kate's dying to get pregnant, but her schedule hasn't allowed it."
The insider said the blonde beauty has also started taking prenatal vitamins and is carbo-loading in the hopes it will boost her fertility.
Earlier this year, Kate admitted she thinks raising a child will be "tough" but insisted she is ready for the challenge.
She said: "I know that it's going to be tough, but Michael and I will find humour in it.
"We're already convinced that our kids will do things that are hilarious."
The 'Big Sur' actress' "maternal instincts" kicked in when she first started spending time with 16-year-old Jasper, her spouse's daughter from a previous relationship.
She added: "After ordering pizza for the third time when she first started coming over, I knew I had to learn how to cook because I wanted to nurture her. These maternal instincts kicked in."

Meanwhile, Lindsay - who forgot some of her lines during the show's first performance - has hit back at her critics, insisting that it wasn't a "disaster".
She explained: "It could've been a disaster - but it wasn't by far.
"I was nervous on the first night because I'd never done it before. But everyone has been really great.
"Every night feels more natural and comfortable. I'm not used to a live audience, it's a much quicker buzz."
The 'Mean Girls' star also admitted she had refrained from reading any bad reviews about the show's debut night.
She said: "Everyone is always going to be judgemental, no matter what.
"I respect people have an opinion, but I'm doing the best I can and will for the duration. I'm doing this because working makes me feel happy and this is a new venture for me."

Gwyneth Paltrow has become a "shoulder to cry on" for Jennifer Lawrence.
The 42-year-old actress - who "consciously uncoupled" from Coldplay frontman, Chris Martin, earlier this year - is offering sympathy to Chris' new girlfriend, after nude photos of the 'Hunger Games' actress were leaked online.
A source told the Daily Star: "When the leaked pictures came out, Jennifer was obviously horrified.

Pixie Lott believes celebrities who cheat with their 'Strictly Come Dancing' partners must lack confidence in their relationship.
The 23-year-old 'Nasty' hitmaker - who is starring in the BBC1 dancing competition - thinks the "curse of Strictly" only affects those who lack faith in their other half but admits she does understand how affairs with dance partners could begin.
She told The Sun: "It is very intimate and you are spending a lot of time together. But if you're confident in your relationship then nothing is going to happen.
"There would have to be something wrong with your relationship in the first place for you to get with your dance partner."
Pixie - who is currently dating 26-year-old model Oliver Cheshire - has insisted her boyfriend has nothing to worry about as she is "not that sort of person".
She added: "He isn't jealous at all. He's got no reason to be.
"He met my dance partner Trent [Whiddon] and they got on really well."
The "curse of Strictly" can be traced back all the way to series one, when rumours stated that newsreader Natasha Kaplinsky was the driving force behind her dancing partner, Brendan Cole's split from his fiancee.
Other contestants including Denise Van Outen, Susanna Reid and Ben Cohen have split from their partners after appearing on the show.
Most recently, it was confirmed that television presenter Rachel Riley has separated from her husband and has started dating her ex-'Strictly' partner Pasha Kovalev.

Simon Cowell has insisted that being a father will not affect how he judges contestants on the 'X Factor'.
The 54-year-old media mogul - who has seven-month-old Eric with partner Lauren Silverman - has revealed that he will judge the hopefuls on their voices and the success of their performances.
When asked if his judging style had changed since the birth of Eric, he told The Sun's TV Magazine: "I don't see how it could.
"I mean, you've got someone who is rubbish, just because you've got a baby doesn't mean you will suddenly say that they're good."
Simon was joined at his Los Angeles mansion by ex-girlfriend and 'So Macho' hitmaker, Sinitta, who helped him whittle down his six contestants in the 'Overs' category to just three.
The 45-year-old singer - who has appeared as an aide on the show for nine of its 11 series - revealed there was a different atmosphere at the house this year.
She said: "It's very different doing Judges' Houses compared to the last time we filmed it here, five years ago.
"The difference is having the baby and the dogs. The house is just warmer, more relaxed."
Meanwhile, Simon has also revealed that he took his final six contestants to see One Direction perform on their 'Where We Are' stadium tour at the nearby Rose Bowl.
He explained: "That was an interesting reality check for them as it was the day before they performed.
"They were at a concert with 60,000 people watching a group who came from 'X Factor'.
"It probably was a bit daunting. It's a lot to live up to, but it is proof that you can do something from this show."

Robert Pattinson sweated like a "crazy person" while filming intimate scenes with Julianne Moore.
The 28-year-old actor - who stars alongside the actress in the new drama 'Maps to the Stars' - struggled to keep his cool on set in Toronto, Canada, during a raunchy sex scene with the flame-haired beauty.
The 'Twilight' star began sweating so profusely that the 53-year-old actress even became concerned for his health.
He told Heat magazine: "That was kind of hilarious - it was the first time I'd met Julianne as well. It was so hot in Toronto and she's one of these people - she doesn't sweat at all! But I sweat like a f**king crazy person. And I was trying to literally catch drops of sweat to stop them hitting her back.
"Afterwards, she was like, 'Are you having a panic attack?' It was so embarrassing."
Meanwhile, Robert also admitted he worried he wouldn't make it in the industry after failing to land any roles for three years when he first moved to Los Angeles.
He explained: "I'd been in LA for three years and not got a job, ever. 'Twilight' was my first job with my American agent, who had a six month turnover rate with clients.
"If you hadn't got a job in six months, you were kicked out of the agency, and my agent really stuck out for me."
