The singer, who performed an awesome tribute to late salsa icon Celia Cruz, headed to the Chateau Marmont in Los Angeles for a fete hosted by the owners of DSquared, according to People.
J.Lo didn't let her high-energy performance earlier in the night slow her down either.
She continued to dance at the event with her boyfriend Casper Smart and pal Leah Remini, according to the mag.
Robert Pattinson also showed up at the party, as well as Akon, Dancing With the Stars' Maksim Chmerkovskiy and music producer L.A. Reid.
