Jennifer Lopez loves being back at work.

The singer-and-actress took a career break when she had twins Max and Emme - her children with husband Marc Anthony - in February 2008 and although she loved spending time with her family, admits she had a great time working on comeback movie 'The Back-Up Plan'.

She said: "I love being back to work, I've always been working and to have left it for a couple of years to have my kids and spend time with them has been a big deal for me, so to get back has been the best."

Jennifer plays an expectant mother in the movie and says she related more to the role because of her own experiences of pregnancy.

She added: "Having just gone through my own experience of having babies for the first time it definitely ranked true to me. All the little jokes about what it is to be pregnant and being tired and being kind of hormonal and all those kind of weird things that happen to you. And, how hungry you are."
