Hey there, I'm Karli Bulnes. Check out Blake Lively channeling Marilyn Monroe in today's PopSugar Rush! Blake Lively impersonates fellow blond bombshell Marilyn Monroe in these new photos from the set of Gossip Girl. The pics provide an awesome sneak peek of the show's 100th episode, with Blake as the center of the Gossip guys' attention. This spot on re-enactment of Marilyn's famous "Diamonds Are a Girl's Best Friend" performance is all part of a dream sequence that takes place during the episode, but Blake isn't the only leading lady who gets to play dress-up. Leighton Meester looks amazing as Audrey Hepburn in her best Breakfast at Tiffany's gear. Blake follows in the footsteps of several starlets who have impersonated Marilyn in the past including Madonna, Jennifer Lopez, Britney Spears, and of course most recently, Michelle Williams. The special 100th episode of Gossip Girl is set to air Monday, January 30th on The CW.
