Uh-oh, Kanye West is going to be incandescent with rage when he discovers that Chris Brown was making a move on his ex, model Amber Rose...

Chris Brown, who has been sentenced to community service after admitting to assaulting Rihanna (but Amber doesn't mind!), was spotted whispering into Amber's ear at P Diddy's July 4 Independence Party held at his LA mansion. We wonder what he was saying...

Meanwhile, the ever 'zaney' Ashton Kutcher was up to his usual japes and was swinging from chains over P Diddy's pool as wife Demi Moore's stretched face tried to form a smile.

Someone allowed Lindsay Lohan near the mic which she left greasy with fake tan.

Happy belated Independence day!
