Bombay Sapphire was on hand to toast the 30-year-old actress, who met up with her Blue Valentine director Derek Cianfrance and The Kings Speech director Tom Hooper inside the bash.

Michelle recently dished on how she chooses her work and what attracts her to certain roles.

“I think when I respond to material, it’s because it’s above me. It’s smarter than I am. It’s talking about things I haven’t kind of figured out, and that’s why I want to go toward it, because it holds my attention for long enough,” she said.

“It’s the distance that I have to cross between myself and the character,” she added, “to something I don’t understand, and I’m working through that constantly.”
