Calvin Harris throws pal's stag do at T in the Park

Calvin Harris recreated a pub backstage at a music festival for his friend's stag do.

While performing at T in the Park, in Perthshire, Scotland, Calvin used the event to celebrate his pal's impending nuptials.

In fact he recreated the pub where his friend Mark Irving works complete with full bar, leather sofas and a pool table in the festival's VIP area.

Calvin put his painful split from Taylor Swift, and her high-profile romance with Tom Hiddleston, behind him to celebrate love with his pals at the Scottish festival at Strathallan Castle in Perthshire.

Calvin told The Hits Radio in an interview: “What's happening now it's my best mate from Dumfries he's having a stag do. So I'm the the best man and I’ve recreated the pub that he works in. It’s a giant stag-do.”

No expense was spared on the make shift pub as Calvin admitted: "We set a team on it," adding he forked out a small fortune to recreate the drinking spot Mark runs in his home town of Dumfries.

It was the DJ's first trip back to his home country this year, so he was clearly keen to make the most of it, especially for the groom-to-be. And Calvin admitted DJ-ing in front of thousands at the festival is definitely not as worrisome as giving the best man's speech at his friend's wedding reception later this year.

“Of course, the speech is more nerve-racking than headlining T in the Park," he told British newspaper The Sun. "It takes a lot more preparation. I have no visuals to hide behind either like on stage. I might get Dizzee Rascal to help me. I’ll invite him along and get him to do a verse," he joked.

Calvin is no stranger to having celebrity guests pop up onstage. At Friday night's Wireless Festival actor Will Smith showed up with his whole family to watch Calvin's set. The actor introduced Calvin at T in the Park two years ago, and did the honors at Calvin's request on Friday night. While rappers Big Sean and Dizzee Rascal made cameos during his set.
