Jenny McCarthy's post-Jim Carrey romance is kaput. The blonde B-lister has called it quits with Las Vegas pirate performer and under-eye-rejuvenation-product entrepreneur Jason Toohey after about four months of togetherness. Her rep confirms the breakup to People but insists they "remain close friends." McCarthy isn't sitting home alone and depressed, however. She reportedly danced up a storm at a pal's Grey Goose-sponsored holiday bash on Saturday night. "I have been so open and truthful in this relationship -- it is amazing," Jenny gushed to the mag in October. "I am staying with Jason because I am happy. If that should change, I will simply leave. I trust my own happiness -- and I will follow my own emotional guide."
