"Gossip Girl" alum Penn Badgley made his Miami Art Basel debut with his band MOTHXR at the Life Of The Party event held at the Brickell City Centre Tuesday night.

Now Brooklyn-based and resident lonely boy no more, he and the band had throngs of female fans hanging on every lyric as they played songs from their new album, including their hits "Victim," "She Can't Tell" and "Touch."

MOTHXR has supported acts in the past such as Streets of Laredo, San Cisco, Sir Sly, Har Mar Superstar, The Neighbourhood and Miami Horror. Their debut album, "Centerfold," was released Feb. 26.
