God I hate her.... Though Thursday marks her 40th birthday, the Playboy cover girl told PEOPLE, â€œI sadly have the same thought that my parents say every birthday which is, â€˜I donâ€™t feel that old.â€™ So, I have decided to make my mindset 40 is the new 15. Okay, fine â€“ the new 22.â€ Dressed as a â€œcougarâ€ â€“ a joke, considering her age â€“ the ever-youthful McCarthy headed to Las Vegas with her sister (also dressed as a cougar) Wednesday to celebrate her birthday at Gallery Nightclub. But one person you wonâ€™t see with her any time soon is a boyfriend, though she has singled out a familiar face that sheâ€™s â€œcourting.â€ â€œI have not met anyone yet that is a potential love,â€ she said. â€œI have myself under construction. Iâ€™ll let you know when the roads are clear and reopened.â€ Since splitting in August with Chicago Bears linebacker Brian Urlacher, her boyfriend of five months, McCarthy still has an open mind about finding romance. â€œIâ€™m in love with falling in love. I have come to realize, though, that I need to practice what I preach and learn to love myself completely before I love someone else,â€ she said. â€œSo, Iâ€™ve been courting myself and aving a great time with me, myself and I.â€ People Magazine.
