Carmen who? Simon Cowell took a harem of five female friends, including ex-fiancée Mezhgan Hussainy, to Bagatelle St. Barts for a late-night dinner Saturday. “The X Factor” judge docked his yacht in Gustavia Harbor before ushering his lovely crew to dinner, where Swedish model Victoria Silvstedt and her boyfriend, Maurice Dabbah, joined up. A spy says the women “went crazy” when a DJ played Carly Rae Jepsen’s “Call Me Maybe,” and Cowell dropped $10,000 on booze alone during dinner by ordering a jeroboam of Cristal. His gal pal Carmen Electra wasn’t there. He reportedly explained the relationship to Ryan Seacrest quipping, “She’s not my girlfriend. We’re people who date.”
