Is this Leslie Mann???….or Carrie?!
Leslie was spotted at Cedar-Sinai Hospital's 8th annual Pink Party at SaMo's Hangar 8 wearing a tiered gown from Rodarte's Fall collection.
While we admire her experimentation, the dripping blood rose neckline just gives us the shudders.
But maybe they're just getting into the Halloween spirit?
