Earlier in the evening Bieber and Gomez were at the premiere of Perry's new flick, Katy Perry: Part of Me 3D, at Grauman's Chinese Theatre. They then stopped by Chateau Marmont with R.Pattz, 26, before heading to Bootsy Bellows.

When they finally called it a night, Pattinson and Woodward almost had to hail a cab.

OK, maybe not. But bodyguards accidentally shut the doors on the celeb-filled van before they got in. They were quickly opened up when Woodward reminded them, "And there's still us."
