Anna Kendrick - Anna Kendrick Starstruck By Jennifer Lopez On Movie Set

The ensemble movie features famous faces including Cameron Diaz, Matthew Morrison and Dennis Quaid, and the Twilight actress was delighted to learn she would be sharing the screen with Lopez.

She jetted to Atlanta, Georgia for the shoot, but felt overwhelmed to be on set with the On the Floor hitmaker.

Kendrick tells Bbc Breakfast, "They flew me into Atlanta one day just for the purpose of walking through frame in one of Jennifer's scenes so that you can tell we're at the same bar...

"I was so excited to meet Jennifer Lopez, who is so beautiful it makes your head wanna explode. It's just unbelievable.

"It was one of her most serious scenes in the film... so she's off in the corner trying to prepare and I'm just like, 'I get to meet Jennifer Lopez, it's the best day ever!'"
