Selena Gomez celebrated her 21st birthday with a celebratory dinner at Bagatelle in West Hollywood last week, but she kept the party going well into the weekend. On Saturday night, the "Come And Get It" singer toasted her big day (and the success of her new album) with a party at the Revolve Beach House in Malibu with pals including Jaden Smith - and, as a surprise to some, her on-again, off-again boyfriend, Justin Bieber. "He and I have had such a history together," she told "Good Morning America" on Friday. "I'll always care about him and protect him."

• Josh Duhamel revealed earlier this month that he and his wife Fergie are expecting a boy, and over the weekend, the couple celebrated with a baby shower in Los Angeles. Guests including Kelly Osbourne, Gabriel Aubry and Adam Lambert packed into the SLS Hotel to toast the parents-to-be. According to People.com, the bar served specialty Patron Ferg-aritas and guests dug into a black, white and blue four-tiered cake. And if that wasn't enough to satisfy everyone's sweet tooth, party favors included blue and white candy.

• When Matthew Perry guest-hosted CNN's "Piers Morgan Tonight" on Friday, he interviewed his former "Friends" co-star Lisa Kudrow - and both admitted that they're nostalgic for their sitcom days. "You could see how much we laughed and everything," he said, "And I tell myself, saying if I can - if I had a time machine I would like to go back to 2004 and not have stopped." Kudrow, who, along with Perry, starred on the series for 10 seasons, agreed. "Oh," she said, "I would keep going!"
