As Hayden Panettiere fights for whales' rights, Ali Larter is fighting for an equally important cause: chocolate!

Showing off a brand new hairdo, the Heroes star spent Tuesday helping to unveil the Godiva Decadence Suite, a hotel room designed with chocolate from top to bottom at the Bryant Park Hotel in New York City.

"It's the perfect bit of sin," Larter said, adding that Godiva chocolate pearls are her "private daily indulgence."

Of course, reports that the actress is the face of the Belgium-based chocolatier's annual Valentine's Day promotion may have helped her become a big fan of the brand.

Meanwhile, a handful of Heroes spoilers suggest that we may have seen the last of Niki, but Larter will be back on the series. We can't wait to find out if that's true (hear that, writers?!?).
