But Leighton Meester wasn't there!
Ahh it's always nice when someone's boyfriend shows them some support, and Justin Bieber has been particularly supportive of girlfriend Selena Gomez recently, cancelling an appearance in Canada to be with her when she was ill, and now attending the premiere of her film Monte Carlo. S'nice innit?

Leighton Meester seemed to be missing from the evening, but Selena and other co-star Katie Cassidy seemed to be having a good time anyway.
