Although they've never really left - seriously, have two days gone by without public appearances by Heidi Montag, Spencer Pratt and company? - The Hills returns to the air this Monday night when season four premieres on MTV.

Here's a look at the first episode:

Music group The White Tie Affair will be appearing.

"Audrina Patridge works at Epic records, where we are signed," leader singer Chris Wallace told OK! earlier this week. "She set up a little showcase for us - we're new to the label - and they filmed it, which is kinda of cool."

Heidi Montag and her giant, fake boobs are back for season four!

Moreover, the band isn't the only one trying to create some beautiful music in the episode. Stephanie Pratt reportedly makes a move on Sean-P, the group's guitarist and programmer. A source said "she was all over him."

Does he reciprocate? Does Lauren Conrad have a new romance this season with Kyle Howard? We'll all need to tune in and find out!
