Paris Hilton was showing off some new bling — a diamond ring with her boyfriend Benji Madden's initials on it (subtle, I know) — at the Vegas opening of Kim Vo Salon on Friday night. Clearly, she wants to make people talk and what better way than a steady stream of rings on that one meaningful finger. Her boy didn't walk the red carpet with her on Friday, but by Saturday they were hitting the clubs hand in hand just days before the Madden twins' 29th birthday on Tuesday. I wonder if Paris and Nicole have anything more planned for their boys?
