It was another very special day for Paris Hilton and her newly 29-year-old boyfriend Benji Madden who sauntered into their sushi lunch hand in hand yesterday. His birthday night was spent at Nicky's fashion show, before stopping by a party Nicole was throwing the other twin, Joel, and then off to the fashion after party. Busy, busy. The elder Hilton girl isn't going to let baby sis have the spotlight for too long, however, as Paris has a press conference with MTV at her house scheduled for this afternoon. Sounds like it's time for us to get ready for the official announcement and subsequent onslaught of her reality show about finding a new best friend?
