It's a good thing that Jennifer Lopez is still on good terms with most of her exes, as she still uses them for inspiration for her work. The actress and singer recently used her ex Marc Anthony when critiquing a contestant on American Idol.

The Latina beauty told a contestant Wednesday to take a cue from her ex-husband when it comes to improving his dance moves.

"Find something that makes you not think about moving," Lopez said. "I know one singer, who I used to be married to, who shakes his leg. Who does just a leg thing and it's just a little thing. But it grounds him in the pocket. I feel like that's what you need."

Meanwhile, it looks like Lopez might have never broken up with another ex, back-up dancer Casper Smart.

According to TMZ, Lopez and Smart broke up to help benefit their careers. Producers supposedly thought it would be a good idea if Lopez promoted her latest film The Boy Next Door as a single woman while Smart was "more appealing single" for his big screen film Street.

TMZ reported, "Jennifer Lopez and Casper Smart did NOT get back together, because we found out they were never really apart. Sources close to the couple tell us ... the break-up they announced in June was a business move. Multiple sources say in the spring they did stop seeing each other, but only for a few weeks."

Even though Smart was insisted that there is nothing going on between them, Lopez is yet to say anything.
