“I have been eating the most boring food you can imagine for months now, and I’m going to destroy some burgers and chocolate cakes in a second – and some beer,” Smith – who even went for a jog Oscar morning – told PEOPLE in the press room. “You have no idea!”

The singer, 23, followed through with his plans at a private party at his house attended by co-winner Jimmy Napes, his mom, dad, sisters, managers and close friends following the show.

“They ordered a bunch of pizza and were all taking shots and sipping on Heineken beers,” says a source. “Sam was dancing around with a bunch of his girlfriends, just celebrating and having a great time.”
