Jennifer Lopez hangs out with Casper Smart

Casper Smart supported Jennifer Lopez on the set of her upcoming movie, 'The Boy Next Door,' this week even though they recently ended their relationship.

The 44-year-old singer, who recently ended her relationship with the 27-year-old dancer after two-and-a-half-years together, was spotted hanging out with him between scenes while shooting, 'The Boy Next Door,' in Los Angeles.

A source told PEOPLE.com: "He was there all night. They were loving together. [They were] very friendly and seemed good."

The 'Booty' hitmaker, who made a whirlwind trip to the east coast of the US to promote her new album, 'A.K.A. where she enjoyed a "very flirty" night out with Maksim Chmerkovskiy last weekend, reportedly asked her ex-boyfriend to move out of her LA mansion before she returned.

But sources close to the former couple previously insisted they would remain close friends, as Casper has formed a close relationship with Jennifer's six-year-old twins, Emme and Max, with ex-husband Marc Anthony.

A friend said: "The kids adore Casper. They have a great dad in Marc and know who their dad is, but they enjoyed being with Casper. It was not a bad breakup so there is no reason why they can't see Casper in the future."
