Having a fabulous humpday, Jennifer Lopez headed over to the Tommy Hilfiger West Coast Flagship Opening After Party in West Hollywood last night (February 13).

The “On the Floor” songstress got all gussied up in a figure-hugging dress and hit up the A-list fete, held at a private club.

Earlier in the evening, J. Lo and her boyfriend Casper Smart also showed up at Cecconi’s for the Topshop Topman LA Opening Party.

On Sunday, Jen and Casper were both in fine form as they walked the red carpet at the Staples Center for the 55th Grammy Awards.
