'Gossip Girl' snags Alexa Chung for final season

"Gossip Girl" has built up quite a roster of fashionable guest stars over the years, from Lady Gaga to Rachel Zoe. In its sixth and final season, the Upper East Siders show no sign of stopping their habit of hanging out with famous folks.

It girl Alexa Chung has been photographed on the set of Season 6 -- and though it's possible she was just stopping by for a visit (like Kristen Bell did a while back, sparking rumors of a long-awaited "Gossip Girl" face-to-face) rumor has it Chung will appear on the show.

UPDATE: Warner Bros. confirms that Chung is set to appear. She's playing herself as part of a story involving Blair's new fashion line.

Chung is best known as a model and fashion designer; pieces from her collaboration with Madewell fly off the shelves. She's also hosted several television series, such as "It's On With Alexa Chung."

"Gossip Girl" returns to The CW on Monday, Oct. 8 at 9 p.m. EST.
