There’s a strict division these days between Gossip Girl loyalists and those who’ve passionately abandoned all things Blair and Chuck.

If you’re still of the former, you’ll catch an appearance from the Plasticines on Monday. The French girl group pops up to play two songs at a very important, um, debut for Jenny Humphrey.

As for fashion, no word on which black number Jenny will wear under her raccoon eyes, but the Plasticines will don custom Alice & Olivia outfits. Looks like the partnership the band formed with designer Stacey Bendet at her SS10 presentation has led to even bigger things.

Will their set be silenced by the looming threesome? That, we can’t tell you.
