Heather Graham's estranged parents blame 'Boogie Nights' for breaking their bond.
Joan and Jim have opened up about their fractured relationship with their daughter and claimed her appearance in the 1997 film - which saw her appearing topless on screen - contributed to its breakdown.
The actor and his co-stars were reportedly three hours late to 'The Hangover Part III' premiere in Rio de Janeiro earlier this week, and when he finally rocked up, Bradley seemed sullen and gave monosyllabic answers on the red carpet.
Bradley Cooper is ''grateful for'' 'The Hangover' franchise.
The 38-year-old actor - who plays Phil Wenneck in the movie series - will miss working with co-stars Zach Galifianakis, Justin Bartha and Ed Helms and director Todd Phillips but says he is happy they were able to complete the trilogy.
Heather Graham won't marry unless she's sure she's making the ''right choice''.
The 43-year-old actress has dated a string of famous men - including the late Heath Ledger and singer Adam Ant - but admits she has never been in a rush to wed because she is content with her own life and doesn't need a guy to validate her existence.
