The 34-year-old star appears in new movie How Do You Know with the two actors and said she enjoyed working with them both.
She said to UK newspaper Daily Mirror: 'It's a tough job ladies, but somebody's gotta do it! Nah, it was great. I mean how lucky am I to work with two of the most funny, attractive, hysterical men?
'I would like get really attached to Owen and the day he had to leave, I just started crying. Then I would do scenes with Paul and I felt as if I was cheating on Owen.
'That felt like a totally different movie, which was nice.'
