Attention all single guys: former Playboy bunny Jenny McCarthy is back on the market! The actress-activist-author and her boyfriend of four months, Jason Toohey, have split, E! reports. "It's true," McCarthy's rep told the website.

The former couple began dating early this summer and even shared a house together in Las Vegas. Toohey, a former fitness model, resides in Las Vegas and once starred as a pirate in Treasure Island's 'Sirens of TI' show. He is also the founder of Eyedews, an under-eye mask treatment.

Things seemed to be going well with the couple as recently as last month when she told PEOPLE: "I have been so open and truthful in this relationship--it is amazing. If he wants Chinese [food] and I don't, I say it. If he wants to go out and I want to stay in and watch 'Dancing with the Stars,' I tell him so. Sometimes we both want to play poker and we have a blast at home."
