Dancing With The Stars' Maksim Chmerkovskiy is partnered with Kirstie Alley this season, who has met both praise and criticism for her changing weight.

But Maksim let loose without his partner at Trousdale lounge Tuesday night. Also at the club as of late were Justin Timberlake and Chace Crawford, though all three were with separate groups.

Alley, 60, has been seen out partying plenty lately, especially at Colony nightclub in Hollywood.
