It’s not every day that you get to celebrate a legendary birthday, and it’s not every day that you are Elton John. But if you checked both of those boxes yesterday, then you had a pretty great night, because some of the most famous and beautiful people around joined you in Los Angeles for a star-studded 70th birthday. Yes, as People is reporting, Elton John’s 70th birthday was attended by some luminaries you’d expect (Katy Perry, Lady Gaga, James Corden, Heidi Klum) and some you might not (host Rob Lowe, Jon Hamm, Jack McBrayer, Ryan Adams). Most important, John was bonne-fêted musically by Gaga and Stevie Wonder, who skipped the traditional version of the song for Wonder’s own “Happy Birthday” (a much more upbeat and party-worthy option, in our opinion). Watch the duet below, and here’s to many more, Sir Elton.
