Fergie got her pointed, painted claws out at the grand opening of Butter NC over the weekend, the New York club's new sister site in Charlotte, North Carolina. All the better to threaten her allegedly cheating husband with?

Fergie and the BEP's, who hosted their concert after-party at Butter NC, following their sold-out arena show in Charlotte, were joined by Nicky Hilton while Lindsay Lohan's former fling DJ Jus Ske worked the turntables.

We just gotta wonder -- how does Fergie do certain things with those nails?
