As much as we loved Béatrice Grimaldi's antics in Season 5, there's a new sister b*tch in Gossip Girl town!!!
And she's played by the same French actress who almost nabbed the coveted Johanna Mason role in Catching Fire — Zoe Aggeliki.
The raven-haired vixen will enter Upper East Side as Steven Spence's sister… or, the sister of the man Serena wants to get dirty with!
We're sure sis won't be too happy about brother's new romance once she learns of Starlena's mischievous ways. You know, like the the nose candy and such!
