Despite breaking up some time ago, E! News reports Jennifer Lopez and ex Casper Smart are still keeping in touch with each other all the time. The dancer choreographer is apparently still living in J-Lo's Los Angeles pad.

An insider close to the "I Luv Ya, Papi" singer told E! News that Smart is "taking his time looking for a new place and doesn't seem to be in a rush to move out." Despite the expected tension between the former lovers however, the source reveals that J-Lo isn't feeling awkward at all. In fact, the singer likes having her ex around.

The "I'm Into You" singer reportedly went back to L.A. for a movie re-shoot and spent four days in the apartment. She and Smart ended up hanging out at home before she left for Miami.The source also said that the "American Idol" judge's friends are "worried" about her. Adding that although the friendly exes don't have plans of rekindling their romance, spending so much time together would make her go back to Smart "because it's so easy for her."

J-Lo supposedly isn't very good at staying single, the source even deemed it "impossible" for the singer. E! News reports the source as saying J-Lo "always needs a man in her life and doesn't know how to be alone."

Meanwhile, the "A.K.A." singer was rumored to be dating another dancer, "Dancing With The Stars" pro Maksim Chmerkovskiy. She has since denied the rumor through Twitter when she replied to the speculation made by Q92.9FM Pittsburgh.

"No I'm not," the singer-actress told the radio station and denied it again when a fan clarified the question.

The mother-of-two and Chmerkovskiy, however, were seen partying together at a club in Connecticut after her concert. An insider told E! News that the pair were just friends.
