Seven pop star BFFs that might make you question your own best friend

Adele has made no secret of her love for Beyonce and now it seems the feeling is mutual.

In a new Adele interview, Beyonce has spoken about her admiration for the UK star, praising her hilarious "comebacks" and how "humble" she is.

Only good can come from this new friendship and Adele and Beyonce are now one of our favourite BFFs in the pop world (even if they're probably not quite there just yet). To mark this hugely important event, these are the most inspirational best friends in pop. Our BFFs are great, but none of them are Selena Gomez...

Selena is a key part of Taylor's squad - even if they did play bitter rivals in Taylor's mega-budget Bad Blood video in 2015.

Taylor posted the cutest photo of her and Selena earlier this year to mark Selena's 24th birthday, showing the fresh-faced duo from the early days of their friendship.

If that wasn't enough to make you green with envy, fellow #TeamTaylor squad member Hailee Steinfeld recently told Radio 1 that the entire crew chats in a private Whatsapp group.

Adele has always been a fan Beyonce (she was seen snogging a Beyonce poster on Instagram) and she recently told Vanity Fair magazine that Bey is her "Michael Jackson".

Beyonce went one better and in the same feature responded with a string of compliments for the UK megastar.

"It is so easy to talk to her and be around her," Beyonce tells the magazine.

"She’s funny as hell and her comebacks are legendary.

"The most beautiful thing about Adele is that she has her priorities straight. She is a gracious woman and the most humble human being I’ve ever met."

Ryan and Ed's friendship is born of pure talent, with Ryan flying from the US to visit Ed in glamourous Suffolk to write music together.

"He had the same exact upbringing in terms of his exposure," Ryan told Radio 1.

"When you're in the middle of nowhere and you don't have a ton of distractions, your escape is music. My Top 40 station, the equivalent of Radio 1 where I'm from, was my only escape.

"When there's less to do, you write songs."

Nick and Demi go way back. They have toured together in 2016, but they first teamed up in 2008 for Disney movie, Camp Rock.

The Jonas Brothers were already a bit of a pop phenomenon by this point, but Camp Rock was the film which introduced Demi to the world.

Demi also appeared on Nick's 2014 solo album, where they duetted on his song, Avalanche.

Most important of all, however, were their 2016 Halloween costumes as Dorothy and The Scarecrow from Wizard of Oz. One photo, so many goals.

Usher is credited with discovering Justin Bieber and has helped mentor him throughout his entire career.

Their support for each other remains strong and when both superstars performed as part of 2016's Live Lounge Month, Justin was tweeting his support for his long term friend.

Justin had dropped his stunning acoustic set the previous day. Both, as you might expect, smashed it.

Justin and Jay have worked together on some seriously big tunes (including Suit & Tie and Holy Grail) but their friendship goes much deeper than just studio buddies.

Justin has previously said that he and wife Jessica Biel enjoy couples nights with Jay Z and Beyonce and says they are "regular" people.

Regular but, you know, global superstars on an enormous scale.

Lady Gaga and Mark Ronson holed up in a recording studio for months making her current album, Joanne, and developed a close friendship during that time.

When Gaga visited Radio 1 Breakfast in September on the day she released her single Perfect Illusion she'd been up all night partying the night before and was planning to carry on the celebrations with Mark later that day in London.

He even phoned the studio while she was on air. He hasn't phoned back for anyone else, not even Little Mix.
