Jennifer Lopez was so worried about the age-gap in her current relationship, she urged her toyboy boyfriend Casper Smart to "go find a young girlfriend".

The singer/actress, 43, has been dating the 25-year-old choreographer since splitting from her husband Marc Anthony in 2011, and admits she is well aware of what critics have said about the age-gap.

She tells People magazine, "I ask him, 'Why don't you go find a young girlfriend and get out of here? What do you want with me?' And you think, 'How long is this gone be?' You think, 'Ok, in 10 years I'm going to be like this and you're going to be like that' and... men at that age are... I think all different things. The truth is we don't know what's going to happen. We're loving this moment right now."

Lopez goes on to credit Smart with helping her bounce back after her seven-year marriage crumbled.

She adds, "I just got out of a big, heavy, devastating thing, and he's helped me heal. He's been there for me... We make each other happy."
