So much for keeping it under wraps — not that Paris Hilton is known for discretion. The heiress looks to be newly in love, with Good Charlotte guitarist Benji Madden. The new duo have been spotted shopping, partying and even lunching with Benji's mom in the past few days. An insider close to Benji tells In Touch that the couple got together at talent agent Benny Medina's birthday on January 24. The insider adds that Benji has been "saying that Paris is the one and that she is crazy about him, too." Will Paris follow in her BFF Nicole Richie's footsteps, who's just had a baby with Benji's twin brother, Joel Madden?
