Ed and Val to Frank and Brad: The most unlikely star friendships
Everyone likes a guest star on stage at a festival and the audience at FYF Festival were treated to something very special indeed when Frank Ocean was joined by Brad Pitt.
He didn't sing, of course, just did some very good face acting as he pretended to be on the phone during Frank's cover of The Jackson 5's Never Can Say Goodbye.
It's an unlikely pairing, but it seems there's a deeper relationship between the two. So on that note, here are some of our favourite, and most unlikely, celebrity friendships.
Frank Ocean and Brad Pitt

Are the Hollywood A-lister and reclusive pop star best mates behind the scenes?
Brad Pitt sat on the side of the stage during Frank's FYF Festival performance. There was no interaction between the two, but there is more to their relationship than a simple festival team-up.
In May 2017, Brad Pitt told GQ magazine that he had been listening to Frank's music after splitting from Angelina Jolie.
"I find this young man so special. Talk about getting to the raw truth," he told the magazine.
"He’s painfully honest. He’s very, very special."
And, when Frank performed at Parklife Festival in Manchester in June, he was wearing a Brad Pitt t-shirt on stage.
We're into this friendship. A LOT.
Ed Sheeran and Val from Bake Off
Ed Sheeran wants to make cakes with Val from GBBO
She says his music inspires her sausage rolls.
Ed Sheeran is mates with just about everyone in the pop world. He's in Taylor Swift's inner circle and just this year has spent time in the studio with the likes of Liam Payne, Rita Ora and Zara Larsson.
But the only friend of Ed's we're interested in right now is Val from the Great British Bake Off.
Since she appeared on the show in 2016, she's been sharing videos of her baking online with the intention of attracting Ed Sheeran's attention.
She has caught Ed's attention before and a reflective post about getting older while making sausage rolls and listening to his music prompted Ed to say it was "exactly why" he makes music.
And now, the pair might be teaming up to bake together. He sent Val a video message suggesting the pair cook together and we can't wait to see them together in Val's kitchen.
Katy Perry and Hillary Clinton
Katy Perry was among a number of US popstars who got political in 2016 during the US election.
But the Swish Swish singer went one step further than most, actively campaigning for Hillary Clinton to win the presidency and claiming her experiences during the election inspired her current era of 'woke pop'.
The two became firm friends during the campaign and Katy even named a shoe The Hillary when she launched a range of footwear in early 2017.
Katy described Hillary as her "hero" when she presented her with a Unicef award in December 2016 and even dressed as the Democrat politician (with her then-boyfriend Orlando Bloom) for Halloween).
Jade Thirwall and ALL the drag queens
Jade from Little Mix turned her obsession with RuPaul's Drag Race into friendships and professional relationships.
"I’m just obsessed with the whole thing," she told Gay Times in 2015, before getting her mission underway.
Jade attended Drag Con (a huge drag queen convention) in Los Angeles as a paying customer in May 2017 and the queens at the event were gushing as much about Jade as she was about them.
More recently, she teamed up with Drag Race's 'AAA girls' for Little Mix's Power video, appearing with iconic Drag Race stars Alaska, Courtney Act and Willam.

Lady Gaga and Tony Bennett
Lady Gaga dropped her biggest pop song in years in 2017 with her single The Cure.
But during her career, one unlikely friendship pulled her away from pop music on several occasions. One of her best mates in the music business is iconic jazz singer Tony Bennett, rather than the divas she's often compared to.
The pair recorded an album, Cheek To Cheek, together in 2014 and Gaga has spoken about how their relationship evolved so much further than the studio.
"I think something I was craving for myself was a truly authentic collaboration, a true artistic exchange," she told Rolling Stone magazine in 2015.
"With Tony I found not only that, but I found a friend. Not only do we spend a lot of time together and make music, but we talk.
"It's been an incredible experience all the way around."

It was a successful period for Gaga. Their album sold more than her most recent release, Joanne.
Miley Cyrus and Wayne Coyne
Between her wild-child days of We Can't Stop and her current era, Miley Cyrus found a kindred spirit in Wayne Coyne, frontman of iconic band The Flaming Lips.
They recorded an album together, called Miley Cyrus & Her Dead Petz - which critics loved, and bonded over their musical talents.
"We've just been getting in each other's worlds," said Coyne about their friendship in a 2015 interview with Billboard magazine.
"We text every day - sometimes three times, sometimes a thousand."
Miley didn't hold back on her feelings for Wayne.
"I am 100 percent in love with Wayne, and Wayne is in love with me, but it's nothing sexual in any way," she told Rolling Stone magazine in 2015.
"That would be the grossest."
