Opposites may attract when it comes to romance, so why not in friendship? Because sometimes friendships are batshit-crazy, that's why. If you were surprised to see Loose Women's Denise Welch partying on down with Jared Leto at Coachella 2016, you ain't seen nothing yet.
Feast your eyes on THESE unlikely celebrity friends - may it spark the hope that one day, you too could be BFFs with an A-lister...
Sid Owen and Adele
Sid was a frontrunner to play godfather to Adele's son, Angelo James, as he's a long-time pal of the singer's partner, Simon Konecki. But the Grammy-winning songstress opted for Alan Carr in the end. Who doesn't want a laughing baby?
50 Cent and Bette Midler
Apparently the Divine Ms M would love to collaborate with Fiddy but fears her rap isn't up to scratch. Philanthropy brought these two together when Mr Cent contributed to her New York Restoration Project.
Bette gushed: "He's one of the newest members of our tribe. He's really made my life worth living. [50] has been with me through thick and thin."
Elton John and Eminem
Elton John evidently saw past Eminem’s historic homophobic slurs to see the real Slim Shady. The rapper reached out to Sir Elton to help him overcome his various drug addictions.
Eminem said: "I talk to Elton a lot. We became friends and I talk to him about things, career-wise.
"He had a substance abuse problem in the past. So when I first wanted to get sober, I called him, because he's somebody in the business... who can relate to the lifestyle and how hectic things can be."
They even performed Stan together at the Grammys back in 2001.
Courteney Cox and Ed Sheeran
The Suffolk-born star says Courteney is "so normal" and restored his faith in Hollywood after a tough start in LA. He even dossed down at her Malibu home back in 2013 to write music for his latest album, X.
Ed admitted: "There was no rent but I made the bed and cups of tea and things like that. If you're staying at your friend's house, you should treat it like your own."
And if Courteney and her rocker fiance Johnny McDaid ever get round to tying the knot, newly ordained Ed is all set to officiate.
Lindsay Lohan and TOWIE hunks Dan Osborne and Jake Hall
Lilo clearly has a sweet spot for TOWIE totty, having been linked to both Dan Osborne and Jake Hall over the past couple of years.
According to The Sun, Lindsay had some "harmless fun" with Dan back in 2014 when she was a surprise hit on the London stage in Speed-the-Plow.
More recently, her rep denied a steamy fling with Jake Hall. It was claimed they spent at night together at London club The Box.
Come on TOWIE producers – get her on the show! We know a trend when we see one.
Beyoncé and Blake Lively
This one takes the cake. Sorry. But we had to mention that bizarre bee cake Blake made to celebrate Beyoncé’s 33rd birthday with the message, "In honor of the Queen of all Bs... I had to make this Meyer Lemon Honey cake. Happy Birthday Beyonce!!! Xxo Blake".
These unlike BFFs joined forces to support women's health, education and justice through Chime For Change. So long may their friendship reign.
Denise Welch and Jared Leto
Corrie's original femme fatale met The Joker at Coachella this year and we were a tad surprised by her new look and cosy pics with Hollywood hottie Jared.
Denise said: "Me and my new best friend watching Matty #Coachella2016 !!! xx"
No doubt Jared is a fan of her son's music as they both watched Matt Healy rock the festival with his band, The 1975.
Kanye West and Mary-Kate Olsen
Yeezy allegedly hooked up with Mary Kate on his 34th birthday and penned some racy lyrics in honour of the blonde (or a blonde in Paris at any rate).
The pair has been spotted hanging backstage at various shows over the years, which isn't so strange given their mutual obsession for all things fashion.
Russell Brand and Helen Mirren
Dame Helen fell for Russell's charms when they co-starred in the film Arthur. The notorious playboy was so taken by his on-screen nanny, he reportly gifted her a diamond necklace. As opposed to a pearl one...
Helen gushed that "women melt in his presence" and "he is the archetypal bad boy, who is really just the best, goodest boy you could possibly meet".
David Beckham and Snoop Dogg
Snoop has said: "I love our friendship. Some people just come together for some odd reason."
But Goldenballs and the rapper share a mutual love of football and hip-hop. So it's no surprise this bromance has stood the test of time – from Becks appearing on Snoop's realty show to kick-to-kick in the park with their boys. Adorbs.
Kris Jenner and Jennifer Lawrence
We'd be surprised if you haven't seen THAT photo of Kris Jenner in bed with Jennifer Lawrence. This unlikely pair came together at a surprise birthday party for J-Law, who's a die-hard fan of KUWTK.
Jen said: "It was the closest I've ever come to losing consciousness.
"I had NO IDEA. I'd never met her before but we've always watched Keeping Up With The Kardashians. And then Kris Jenner and I sang Build Me Up Buttercup on karaoke and took that picture."
AMAZING.
Peter Andre and Chris Brown
This one could have lead to the strangest music collaboration of all time. Pete and bad-boy Chris became mates a few years back when Pete was Stateside making new music. We assume they shared a recording studio.
At the time, Pete said: "It's been really fun hanging out with him though and we've had some good chats."
Rather you than us, Pete.
Vas Morgan off TOWIE and ALL the celebs
From Lindsay Lohan to Taylor Swift, Jourdan Dunn, Rita Ora and Kendall Jenner… Vas' Insta is a bizarre who's who of A-listers and party gals. If he's not your best mate yet, don't worry: we're presuming there's some sort of rota system so Vas can befriend EVERYONE IN THE WORLD.
