Oh to be Serena van der Woodsen.
In a dream sequence to air during Gossip Girl's 100th episode on January 30 (8 p.m. ET on CW), Serena (Blake Lively) struts her stuff as the late Marilyn Monroe during a rendition of "Diamonds Are a Girl's Best Friend."
The blonde beauty, who's surrounded by her male suitors including Dan Humphrey (Penn Badgley), Nate Archibald (Chace Crawford), Chuck Bass (Ed Westwick), Prince Louis (Hugo Becker) and several others, is decked out in piles of dazzling jewelry and a red strapless gown with matching opera-length gloves.
Also in the sexy montage? Blair Waldorf (Leighton Meester) dressed as another late, old Hollywood icon, Audrey Hepburn.
Yahoo TV writes, "According to executive producer Josh Safran this Marilyn number has been something he's wanted to film since the show's first season. 'It's something we've never done before. From Season 1, I said, 'I want to do this.' But it just wasn't the right time. I've been pushing it for five years, and it finally happened.'"
