Jennifer Lawrence though she was being pranked over BAFTA win

Jennifer Lawrence thought her BAFTA win was a prank.

The 23-year-old star was in the "middle of being painted blue" while filming re-shoots for her role as Mystique in the 'X-Men: Days of Future Past', in Montreal, Canada when she received the call explaining she'd won Best Supporting Actress at the awards evening which took place in London on February 16.
