Jennifer Lopez's new film does not have a profound message.

The 40-year-old singer and actress admits 'The Back-Up Plan' - which tells the tale of a single woman who becomes artificially inseminated the same day she finds the love of her life - says the movie is a romantic comedy many will be able to associate with.

She said: "It's not a message movie. It's a romantic comedy. It definitely deals with modern issues, which I love. When I read it, that's one of the things I really liked about it, it had a very modern voice. It seemed very up to date.

"I think that's very important for romantic comedies - that they do deal with issues. It doesn't feel like it's a story from 20 years ago, which some romantic comedies can be like. So, that was one of the things that really attracted me to it."

The mother-of-two also admits the movie imitated her own life because of her pregnancy with twins Max and Emme, two.

She said: "So many things in this movie were art imitating life for me because I had just gone through the pregnancy. It was just fresh in my mind. When Kate Angelo wrote The Script, she had just gone through a pregnancy as well.

"She came up to me and I had just signed on to the movie. I was really excited about it."

'The Back-Up Plan' is released May 7.
