A new pot-stirrer is headed to the Upper East Side, and she’s threatening to derail Blair Waldorf’s big fat royal wedding.
Sources confirm to TVLine exclusively that French actress/model Roxane Mesquida (Kaboom) is joining the cast of Gossip Girl as the meddling sister of Blair’s fiancée, Prince Louis.
Little else is known about Mesquida’s princess character, save for that fact that she is not happy about her brother’s impending union and is hell-bent on sabotaging it. Oh, and the role is recurring, so she’ll be around long enough to do some damage.
