Jennifer Lopez and Marc Anthony proved that sometimes exes can get along just fine, as they reunited on stage during Anthony's NYC concert over the weekend. The former couple and forever friends rocked Radio City Music Hall with their "No Me Ames" duet.

The crowd erupted into ear-bleeding screams as J. Lo emerged out of nowhere perform the 1999 joint single, which appeared on her debut album On the 6. “The queen!” Anthony exclaimed as the diva exited the stage.

Anthony and Lopez have been friends for a long time, and got married in 2004 before splitting in 2011. Their divorce was finalized three years later. The artists have 8-year-old twins together, Emme and Max. Since then, Anthony remarried and Lopez recently ended things with her beau Casper Smart.

“#MiGente, thank you to the fans and @jlo for a wonderful concert #AllAboutFamily backstage last night at @radiocitymusichall," Anthony captioned his Instagram photo that featured the kids, Lopez and his third wife Shannon De Lima backstage at the concert. How's that for a family bond?
