AMFAR gown event lace Jennifer Lopez

Jennifer Lopez attended the 2013 amfAR Inspiration Gala at The Plaza Hotel in New York City last night, and the 43-year-old actress looked incredible in blue lace Tom Ford dress.

Jennifer tweeted, "Change can happen when we come together. Looking forward to tonight’s #amfARInspiration NY Gala to benefit #HIV #AIDS research!!! What a beautiful evening at #amfARInspiration! So humbled to be honored by these agents of change. When we come together, there's no stopping our fight against #AIDS. Thank you @OfficialALT @amfar."

J. Lo was joined at the event by designer Kenneth Cole, who is on the board of directors of the organization, but her sexy dancer beau Casper Smart was nowhere to be found.
