Liz Lemon And Jack Donaghy Romance Clues In The New 30 Rock Promo?

The season premiere of 30 Rock is just four and a half weeks away — so close that NBC is already running promos for it to mercilessly tease us. I didn’t notice this part when the promo aired during The Office the other night, but what is going on at the :10 mark? Are Liz and Jack cuddling here? (Sorry about the poor quality):


I’m 90% sure this is footage from the new season — it looks like they’re re-enacting part of the Dirty Dancing dance!
