Robert Pattinson didn't party till the breaking of dawn, but we imagine he enjoyed his cozy little birthday shindig.
In fact, a Snow White junket took up all of Stewart's time yesterday ahead of the film's world premiere tonight, calling into question whether she made it back to the hotel in time for Pattinson's party.
Oh, of course she did!
Stewart returned to Claridge's at 5 p.m. and was on hand to help her man celebrate, as were Pattinson's mother, father and sister, a very pregnant Sienna Miller and her fiancé (and Rob's best pal) Tom Sturridge.
The party broke up at around 1 a.m., time for Snow White to spend some alone with Prince Charming.
