Pharrell Williams, Alicia Keys and Kendrick Lamar have collaborated on a new song.
The 'Happy' hitmaker has produced a new track, 'It's On Again', which features Alicia and Kendrick and will appear on the soundtrack for upcoming superhero action movie, 'The Amazing Spider-Man 2'.
Acclaimed Hollywood score composer Hans Zimmer is overseeing the project and has worked with the talented trio on the song.
Alicia said: "I'm very excited to be a part of such a powerful collaboration with Kendrick Lamar, Pharrell Williams and Hans Zimmer.
"This is the next chapter in the 'Spider-Man' legacy and we really feel 'It's On Again' captures the experience, the story - and most importantly - the meaning behind the film, which is that we all have the potential to be extraordinary. There's a little bit of a super hero in all of us."
'No One' singer Alicia provides the main vocals on the track, but Grammy-nominated rapper Kendrick is heard in one of the verses.
Pharrell gushed about his collaborators, saying: "Hans has created an iconic score theme and it was exciting to collaborate with him again on this song. When I was making the song, I knew Alicia and Kendrick had to be on it. They take the song to a whole new level."
The singer-and-producer was recently nominated for an Oscar for his last soundtrack song, 'Happy', which appeared in 'Despicable Me 2'.
In addition to 'It's On Again', Pharrell, 40, also enlisted Alicia for 'Know Who You Are', taken from his just-released second studio album, 'G I R L'.

Joe and Anthony Russo will direct 'Captain America 3'.
The Russo brothers helmed the forthcoming sequel to 2011's hit film - titled 'Captain America: The Winter Soldier' - and are "getting an idea" of how they want to approach the next installment.
Talking to collider.com, they said: "Well now that Kevin [Feige, President of Production at Marvel Studios] said it that means we can talk about it, I guess. That's great. We're just in the formative stages of it right now. We just started breaking story with [screenwriters Christopher] Markus and [Stephen] McFeely and we're just getting an idea of what we wanna do with it."
They admitted it's "crazy" working on the third film, since 'Captain America: The Winter Soldier' is yet to hit the big screen.
The superhero adventure, which stars Chris Evans as the titular character who is also known as Steve Rogers, will be released in Los Angeles later this month and in North America this April.
They added: "It's crazy working on it before the movie even comes out because you want to see what people respond to in the movie. You want to get some inspiration from what people like about the film so you go, 'Okay, this is what we gotta lean into in the next movie' or 'this is what we should move away from, this didn't work so well.' So we're just in that phase of breaking story but waiting to see how people respond to the movie."

Scarlett Johansson says 'Avengers: Age of Ultron' is a "continuation" of 2012's hit film.
The actress plays Black Widow, aka Natasha Romanoff in the films, and has revealed the characters grow whereby the are able to take the "next step" in the forthcoming Marvel picture, which is due for a May 2015 release.
She told collider.com: "I mean this movie feels like the continuation of 'The Avengers', it doesn't feel like a tag-on or the rehashed version or just 'let's throw a bunch of new characters in there and keep the thing alive.' It really feels like the next step, and all of our characters, our relationships with one another continue to progress, become more intertwined, more complicated, more meshed."
Johansson also gushed about director Joss Whedon who has come up with a "totally solid" and "ever-expanding Marvel universe".
She explained: "I was just amazed -- Joss is something else, he really is. He locks himself away for God knows how long, I think he has the dark circles to prove it. [He] just came out with something totally solid. I was really impressed by his ability to make this ever-expanding Marvel universe feel very close-knit and cerebral and progressive."
Johansson is hoping fans of the comic will "love" the film's "dramatic moments" which the viewers can relate to.
The star added: "And the film has a lot of great comic book moments that the fans are gonna love, but it's also got a lot of really great dramatic moments that audience members, I think, will really relate to."

Kristen Bell hopes the 'Veronica Mars' movie "satisfies" fans.
The 33-year-old actress - who reprises her titular role in a movie spin-off of the cult classic TV series - admits she feels a responsibility to ensure fans that helped finance the film through crowd-funding website Kickstarter enjoy it.
'Veronica Mars' made headlines last year after Bell and show creator Rob Thomas raised over $5 million from avid viewers of the show, which ran from 2004 to 2007, to fund the big screen production.
Quizzed if she's nervous about the film, Bell said: "Our Kickstarters who funded the movie are my priority, so I'm a bit nervous ... [well] not nervous, but I'm hoping that everybody leaves the theatres satisfied.
"If new fans like it or people [who] didn't Kickstart the movie, that's just an added bonus for me."
The film picks up several years after the TV series ended and sees private investigator Veronica return to her hometown of Neptune, California, to solve one last crime when her former high school flame Logan Echolls (Jason Dohring) is charged with murdering his girlfriend.
'Veronica Mars' will feature numerous cameos from A-list stars including James Franco, Jamie Lee Curtis, Justin Long and Bell's husband Dax Shepard.
The actress gushed to Access Hollywood: "We just made a bunch of phone calls and asked people to be involved. We just lucked out that everyone wanted to be involved."

Robin Thicke partied with Leonardo DiCaprio for his 37th birthday.
The 'Blurred Lines' singer - who recently split from wife Paula Patton after eight years of marriage - was joined by the 'Wolf of Wall Street' actor and a group of male friends at DBA nightclub in West Hollywood on Monday (10.03.14), and despite the problems in his personal life, he had a "great" time.
A source revealed: "[Robin was] in a great mood, enjoying time with his friends, [but] no girls were allowed in their booth."
Robin and Leo indulged in a slew of alcohol, with the group sipping on tequila pineapples and Amstel light beer before toasting the occasion with Cristal champagne.
The no-girls policy could be part of Robin's attempts to win back Paula - with who he has three-year-old son Julian - as it was recently claimed she had told him to "prove" he is serious about wanting to save their marriage.
The 'Baggage Claim' actress had initially been insistent about wanting a divorce following her increased unhappiness at her spouse's hard-partying ways, including being pictured with various women while out socialising, but is said to have had a change of heart following "constant" conversations about their future and is now open to a reunion.

Dita Von Teese has a "uniform" to feel sexy in.
The burlesque star - who was previously married to Marilyn Manson and also dated French aristocrat Louis Marie de Castelbajac - always turns to certain garments with very particular cuts when she wants to feel her best.
She said: "I have a distinctive aesthetic of what I think is sexy, and I have kind of a uniform. It's usually something that shows a little bit of cleavage and possibly has long sleeves. I like to wear long, black, leather upper glove and black long-seamed stocking. I like to have my hemline just below the knee, and I like a perfect Louboutin pump."
The 41-year-old beauty also insists it is important for people to be sexy for themselves, rather than seem like they are making too much effort for their partner.
She told Harper's Bazaar magazine: "Seduction is at its finest when it's nonchalant. You have to make him believe that you just are that way. So when you think, 'I'm going to try some garter belts on for him, and I think he'll like this color,' you've missed the whole point.
"But if you're indulging in things that make you feel good about yourself, and that are also beautiful and luxurious and fit you well--things that you would wear every day whether or not someone's looking--that's when it becomes natural and effortless. And that's when you really get him where it hurts."

Ricky Gervais wants to host the Golden Globe awards again.
The 'Muppets Most Wanted' actor's stints of fronting the ceremony in 2010 2011, and 2012 saw organisers come under fire for his daring gags about stars including Ashton Kutcher, Kim Kardashian and Mel Gibson, so thinks it is best to wait until the controversy is completely forgotten before he takes the helm again.
Asked by 'Access Hollywood' if he would host the show again, he said: "I wouldn't mind. Well, not yet, but, yeah. Give it a few years. Let everything [settle]."
It seems Ricky - who was replaced as host by Tina Fey and Amy Poehler - has had a change of heart as he previously vowed not to front the ceremony again.
Speaking after his third stint in 2012, he said: "Thank f**k that's over. I had a blast actually. It was by far my favourite of the three hosting stints.
"I've told my agent to never let me be persuaded to do it again though. It's like a parachute jump. You can only really enjoy it in retrospect when you realise you didn't die and it was quite an amazing thing to do."
However, in 2011 he ruled out fronting the ceremony for a third time and later changed his mind.
When asked that year if he would host again, he replied: "It's doesn't really matter because I'm not going to do it anyway. I said I wouldn't do it a second time but I think twice is enough."

Will.I.Am and Pharrell Williams have resolved their use of 'I Am' out of court.
The pair were locked in a legal battle after the Black Eyed Peas star issued a cease and desist letter which demanded his Interscope Records label mate stopped using the phrase 'I AM' in relation to his 'I AM OTHER' YouTube channel.,
Pharrell hit back with a lawsuit in an attempt to protect his right to use the moniker - before will.i.am counter sued and claimed he has a copycat history.
The 'Scream & Shout' hitmaker cited the producer's record label 'Star Trak Entertainment', and that he also faces legal action from Marvin Gaye's family for allegedly ripping off 'Got to Give it Up' for 'Blurred Lines', his hit with Robin Thicke.
In his case, will.i.am also claimed Pharrell tried to register the trademark 'Pink Slime', which he insists is too similar to 'Slime', owned by toy manufacturers Mattel.
However, the parties have informed a judge that they had reached an agreement and are in the process of drafting a settlement, according to The Hollywood Reporter.
Robin Thicke - who co-wrote 'Blurred Lines' - previously took legal action against Marvin Gaye's family and insisted in his case that the tracks bore "no similarities" to each other.
The lawsuit cited: "There are no similarities between plaintiffs' composition and those the claimants allege they own, other than commonplace musical elements.
"Plaintiffs created a hit and did it without copying anyone else's composition."

Chris Pine has been charged with drink driving.
The 'Star Trek' actor was stopped by police in a "routine operation" in Methven, Canterbury, New Zealand, on March 1 and was arrested after allegedly being found to be over the alcohol limit.
He will appear in Ashburton district court on 17 March, and local police said no further information will be released about the case yet because the matter is before the courts.
The 33-year-old star was in the country filming 'Z for Zachariah' and had reportedly been out celebrating the end of the shoot the night before he was arrested.
Blue Pub Methven manager Casey Crawford said around 70 cast and crew members, and local volunteers had hired the nightspot on February 28, with the party ending around 3am on March 1, the morning the actor was arrested.
Mr. Crawford told the New Zealand Herald newspaper: "Chris Pine arrived here and had his supermodel girlfriend [Iris Bjork Johannesdottir] with him and he spent most of his time with her, she flew in that day someone told me.
"You can see the photos behind the bar with our staff and he looked fine, I only ever saw him drinking tap beer and his partner she was just drinking sav wine.''
He also said the cast and crew were "subdued" during the evening, and there were designated drivers appointed, so he was surprised Chris took the decision to get behind the wheel.
