Jennifer Lopez may be promoting a new movie in which she seduces her neighbor but her real-life neighborly relations may be chillier. The actress, singer, and American Idol judge is in hot water after her ex-boyfriend Casper Smart’s dog escaped from her house and bit a neighbor.

TMZ reports that the dog, a boxer named Bear, was staying with Lopez in December when he escaped from her Los Angeles area home. He bit a female neighbor, clamping down on her arm and breaking her hand.   The dog has been isolated in Smart’s home since the incident and animal control authorities are investigating to determine if it is a threat to others.

Lopez and Smart have both said their romantic relationship is over but TMZ claims the dog still visits Lopez frequently to see her two children. It is not yet known if either Lopez or Smart were home at the time of the incident but Smart, as the legal owner, was given a citation for an unleashed dog. He has not commented formally on the event.

Lopez has been making headlines for her romantic interests lately. Her latest film, The Boy Next Door, tells the story of an older woman who has a one-night-stand with her younger neighbor. Despite the willingness of the media to label her a “cougar,” Lopez has no interest in embracing what she says is a sexist title.

“There’s like guys who just go after younger women. They have no name,” Lopez told Ellen DeGeneres in a recent trip to her talk-show. “No label.  And you can date one person.  Label.”

The Boy Next Door opens Friday.
