Hello, It's Me! Katy Perry, Orlando Bloom, Jennifer Lawrence and More Attend Adele's Special L.A. Concert

The stars aligned a very special Adele show on Friday.

The audience of the "Hello" singer's concert at the Wiltern theater in Los Angeles was a veritable who's who of Hollywood, but Adele was more interested in connecting with the rest of the concertgoers.

The Vogue cover star was spotted peeking out of an open window of the theater after the show, waving to the fans below and taking pictures of them on her phone. Amid the fans' loud cheers, she held a finger to her mouth to shush them so she could say a few words of thanks to the intimate gathering.

Those lucky fans were even luckier to be in attendance at the kickoff of Adele's world tour – they had to compete with some of Hollywood's biggest stars to snag a ticket. Not only were Adele's close pals Jennifer Lawrence and Emma Stone, accompanied by Woody Harrelson, at the show, but so were Katy Perry and rumored new boyfriendOrlando Bloom.

Perry's former flame John Mayer also attended the show with somebody new: The singer was spotted leaving the Wiltern with a mystery woman.

Tom Hanks, too, reveled in the soothing power of Adele's voice, writing on Facebook, "Adele. What a show. What a voice. What a woman. What an artist. What a date! Thank you."

Weren't able to find a way into the show? No problem – we'll all get a mini Adele concert in our living rooms when she performs at the Grammy Awards on Feb. 15 (8 p.m. ET) on CBS.
