Jennifer Lopez [1] officially kicked off her Las Vegas residency on Jan. 20 with her man, Casper Smart, by her side. The superstar singer and Shades of Blue actress [2] blew us away with her sexy debut performance [3] at Planet Hollywood Resort and Casino, but her tender moments with Casper at the afterparty at Mr. Chow made us swoon.

Wearing a low-cut, long-sleeved white dress and a sleek ponytail, Jennifer stunned next to her longtime love, who rocked a chic tux and bow tie, and, at one point, even adorably reached over to move a hair out of J Lo's face. Talk about couple goals!

This red carpet moment comes just a couple of weeks after the duo's showstopping Golden Globe Awards appearance [4] and is just one of many sweet moments they've had [5] over the years. Keep scrolling to see more afterparty pictures, then check out all the sexiest dresses [6] Jennifer has ever worn.
