Asked who is hottest actor she has ever worked with, the brunette beauty, who starred alongside previous Sexiest Man Alive winners George in 'Gravity,' Ryan in 'The Proposal' and Bradley in 'All About Steve,' told BANG Showbiz at the UK gala screening of her new movie at Curzon Mayfair in London on Thursday night  that it was impossible to choose between the three heartthrobs.

She said: "I would never compare any of my perfectly hot co-stars, who are equally hot and amazing, to each other."

The Oscar-winner then added: "Melissa McCarthy's the hottest co-star of all time! Melissa McCarthy is my hottest co-star."

Melissa revealed that she and Sandra became firm friends while shooting the film because they both have quirky personalities.

She said: "We had little time to enjoy [during filming], but the way we enjoy our life is exactly the same. I never thought I'd meet someone that was as... I don't want to use the word twisted [as me]; the word 'off' might be more appropriate. We both have the same life sensibilities, and the same things we love to do, so it was a kindred spirit. I was very lucky. You don't get that."

The actresses were joined by their co-stars Jessica Chaffin and Jamie Denbo at the screening, as well as the movie's director Paul Feig, who said Melissa and Sandra's great chemistry made their set a lot of fun.
He explained: "The great thing is, the girls got along great. They're still really close friends and that chemistry just kind of took over the whole time. It made it very fun. We laughed a lot."
