Playboy boss Hugh Hefner has confirmed he and girlfriend Holly Madison are trying for a baby. The 28-year-old model sparked reports she was pregnant last summer (Jun07) when she pulled out of TV interviews at the Monte Carlo Television Festival in Monaco due to sickness. She then spent the interviews she did sit for chatting about babies, telling reporters, "I want to have kids with Hef in the next year or so... He's the best lover I've ever had." More recent reports suggested Hefner and Madison have sought fertility treatment in an effort to get pregnant, but the couple hasn't given up on having a child naturally. She says, "We do want a baby. There has been lots of trying! My perfect Valentine's Day present would be a house and a kid." Madison is one of three girlfriends currently enjoying the 81-year-old Playboy boss' company - but he insists she's his number one. He says, "I love Holly the most. Five or six years ago, she was simply one of seven girlfriends, but... I fell deeply in love with her. She's the relationship that will last the rest of my life."
