Jennifer Lopez is finding her groove in the days following her split from Casper Smart. The chart topper joined ex-husband Marc Anthony onstage during his New York City tour stop at Radio City Music Hall on Saturday evening, proving once again that these two can remain friends and support each other’s careers without second thought. JLo and Marc performed their Latin pop hit “No Me Ames,” a song that came out five years before the former couple even started dating. Fans were absolutely loving the surprise duet, which featured the “Ain’t Your Mama” singer in a plunging black sequined gown. Hot mama, indeed. The duo’s 8-year-old twins Max and Emme were also in the audience cheering their talented ‘rents on, and posed for an extended family photo backstage alongside Anthony’s wife Shannon De Lima. And if the 47-year-old is hurting after saying goodbye to her on-again, off-again boyfriend of five years, she sure isn’t showing it. Just one day after E! News reported that the relationship had come to an end, Jennifer was spotted beaming from ear to ear while out and about in the Big Apple. Conversely, the professional dancer-choreographer was photographed hours later wearing a hoodie in an effort to be as under the radar as possible. Relationship drama aside, Anthony put it best with his own Instagram photo commemorating the special moment that included the hashtag, “#AllAboutFamily.”
