(Cover) - EN Showbiz - Eva Mendes doesn't think anyone has "figured out" romance yet.

The Hollywood beauty is delighted with her new movie, Last Night, as it captures the complexities of adult relationships. Sam Worthington and Keira Knightley star as a seemingly happily married couple called Michael and Joanna Reed. Complications arise with the introduction of Eva's character Laura, who is Michael's new co-worker.

"From my own life?" responded Eva, when asked by Look magazine if she used personal experience for her character. "No! I think relationships are so complicated anyway. Nobody has figured any of that out."

While Eva hailed the forthcoming drama, she admits she has no idea how she would react if her long-term partner cheated on her. She has been with her boyfriend, filmmaker George Augusto, for nearly ten years.

"I don't know! I'm going to quote my character here, I suck at hypotheticals!' No, just kidding. I don't know, honestly," she said. (C) Cover Media
