The truth about Chris Martin and Simon Pegg's relationship

What do Coldplay singer Chris Martin and Shaun of the Dead co-writer and star Simon Pegg have in common besides being British? A lot, if their friendship is any indication! Fans might not know it, but Martin and Pegg are close friends, and they have been for years. A quick Google search of the two stars' names returns a number of videos of Pegg performing with Coldplay, and they're pretty entertaining to watch. The World's End star might not have the musical prowess his pal does, but he more than makes up for it in spirit.

"He's one of the most decent people I know. He has this compulsion to make other people feel better," Pegg told The Daily Mail of Martin in 2014. "He is incapable of tolerating other people's unhappiness." The interview was one of many times the two celebrities have spoken fondly of each other over the years. From movie cameos to sweet Twitter photos, Martin and Pegg are practically family after all this time. Here are a few things you probably did not know about their years-long friendship.

Simon Pegg is Chris Martin and Gwyneth Paltrow's daughter's godfather

Like many couples, Gwyneth Paltrow and Chris Martin asked a close friend to be their daughter Apple's godfather when she was born. However, not many children are lucky enough to have a big-name star like Simon Pegg step into the role. But it sounds like Pegg — and his brand of comedy —are up for the challenge. "I'd like to think I'm a really great, fun godfather," Pegg told the Irish Examiner in 2007. "It's much more interesting than trying to be a good influence on her. I'm a comedian — it's what they expect."

Pegg and his wife, Maureen McCann, returned the honor when their daughter was born. The Coldplay singer is godfather to Pegg's daughter, Matilda. He even performed a song dedicated to Matilda when she was a baby. "[Chris] sang a song for [Matilda] in Berlin when she was born," Pegg told People in 2013. "He dedicated one of the songs, and I was really chuffed about it." He also told the magazine that he loved bringing pastries to Apple and Moses Martin, because what are godparents for if not helping kids sneak a little junk food?

Chris Martin made a cameo in Simon Pegg's 'Shaun of the Dead'

Coldplay singer Chris Martin appeared in the 2004 horror-comedy Shaun of the Dead, though it wasn't as a zombie, as some fans might've thought. Instead, Martin appears as himself toward the end of the film, at which point he shares his support for the fictional zombie charity Zombaid. "Chris and [Coldplay guitarist] Johnny Buckland came along and sent themselves up as zombie sympathizers," Simon Pegg told Yahoo! Entertainment in 2019. "But no, Chris Martin was not a zombie in Shaun of the Dead."

On social media, fans often claim that Martin played a zombie in the movie. But, while that isn't the case, the Coldplay singer did have a role in the cult-classic film. Between Martin's Shaun of the Dead appearance and Pegg's performances with Coldplay, the two stars have always been fine with mixing their personal life with their professional roles. And it's a real treat for fans to be able to see them show up in each other's projects. Martin and Pegg's friendship has spanned years, and it looks like these two will be pals for life.
