Fresh off of a big weekend in which her movie "The Roommate" topped the box office, Leighton Meester got another week of work duties underway on the "Gossip Girl" set in New York City on Monday (February 7).

The brunette beauty looked a bit tuckered out as she readied to film scenes alongside co-stars Penn Badgley and Katie Cassidy.

The outing comes as fans can look forward to a new "Gossip Girl" episode airing tonight on The CW at 9/8c.

Titled "Panic Roommate," a synopsis via the show's website reads: "Blair (Leighton Meester) enlists Nate's (Chace Crawford) help to win over her high-strung boss, Epperly (guest star Caitlin Fitzgerald), at W Magazine. Damien (guest star Kevin Zegers) stirs up more drama on the Upper East Side. Chuck (Ed Westwick) finds himself torn between business and pleasure. Florence and the Machine performs an acoustic version of 'Cosmic Love.'"
