I guess she's not quite ready to put on her dancing shoes!

Kirstie Alley, who was just announced last night as one of the 11 castmembers for the new season of Dancing With the Stars, arrived at STK to party with the rest of the ballroomers totally barefoot!

Someone should tell Alley, who should expect to lose more weight dancing on the show than she did with Jenny Craig, that not only will she have to wear shoes in the ballroom, but most likely she'll have to wear heels!

Alley was joined by season 12 pros like Mark Ballas, Chelsea Hightower and Lacey Schwimmer, and of course, by fellow competitor, Kendra Wilkinson, who showed off her ballroom assets:
