Jennifer Lopez just can't seem to shake off Casper Smart completely.
According to People, the 27-year-old backup dancer was by Lopez's side after she returned to Los Angeles this week to wrap up her upcoming film, The Boy Next Door.
"He was there all night," a source told People. "They were loving together. [They were] very friendly and seemed good."
The reunion doesn't come as a surprise as a close friend of Lopez and Smart said the two would remain close despite their decision to end the relationship.
J.Lo has recently been linked to Dancing with the Stars pro Maksim Chmerkovskiy, whom she was spotted with enjoying a "flirty" night out.
