17 Celebrity Cameos On ‘Gossip Girl’ You Probably Forgot About

New York City is a home and a hub for celebrities across all industries, and the glitzy appeal of Gossip Girl’s NYC is made all the more glamorous by its numerous celebrity cameos. Given that Blair and Serena run in the upper echelon of the city’s It girls, it actually makes total sense for them to be rubbing shoulders with Alexa Chung and Lady Gaga. You never know who you’re going to run into on the Upper East Side — and in Gossip Girl’s case, you may not even remember half the celebs you meet.

Over the course of six wonderfully melodramatic seasons, Gossip Girl racked up quite a stacked cast list on IMDB. From stars with recurring roles to those who pop in to play themselves for one scene, here are 17 celebrities who appeared on Gossip Girl that you probably forgot about.


Scroll down to see all the celebrity Gossip Girlcameos we're totally obsessed with!

1. William Baldwin

Serena van der Woodsen’s got some serious daddy issues. One of Gossip Girl’s longest subplots is Serena’s search for her father, who essentially walked out on her when she was a kid. He finally appears for the first time in Season 3 Episode 19 (“Dr. Estrangeloved), where he’s played by a member of one of NYC’s royal families, William Baldwin. (In case you’re wondering, he’s Hailey Bieber’s uncle.)

2. Lady Gaga

You probably blocked out the time Blair and Dan put on a jukebox version of Snow White at NYU given that the whole ordeal was painfully cringe. That means you probably also blocked out the fact that real-life NYU alum Lady Gaga gives a dead-eyed performance of “Bad Romance” at the end of the episode (Season 3 Episode 10, “The Last Days of Discostick”).

3. Hilary Duff

Also included in the Season 3 NYU timeline is Hilary Duff as Olivia Burke. Olivia’s a famous actress who balances attending NYU, starring in the vampire romance franchise Endless Knights, and dating Dan. She’s basically the Gossip Girl universe’s hybrid of Kristen Stewart and Emma Watson.

4. Sebastian Stan

Okay, there’s absolutely no way you forgot this one. Before Sebastian Stan was the MCU’s BB, he was Gossip Girl’s lesser-known CB — Carter Baizen. Stan played St. Jude’s sleaziest graduate and one of Serena’s most questionable exes from Seasons 1 through 3.

5. Karlie Kloss

Karlie Kloss will always attend a NYFW party — even if that party only exists within Gossip Girl’s Season 4 premiere (“Belles du Jour”).

6. Armie Hammer

Welch’s performance of “Cosmic Love” in Season 4 Episode 14 (“Panic Roommate”) was reportedly due to her real-life friendship with Blake Lively.
