'I THOUGHT HE was on the wagon," whispered guests at Philadelphia magazine's Let's Do Cocktails competition Thursday at the Loews Hotel when they saw 94 WYSP's Danny Bonaduce swilling cocktails with abandon.

Indeed, the Broomall-born Bonaduce has publicly struggled with alcohol and drug abuse, but he talks about drinking on the air.

When we told Bonaduce about the stir he was causing, as he judged the contest accompanied by fiancee Amy Railsback, he joked, "I don't drink. I only use it to wash down the pills."

Fox 29's Jennaphr Frederick, KYW 1060's Hadas Kuznits, 95.7 BEN-FM's Marilyn Russell, attorney and BorgataTV.com host Erin Elmore, former "Next Food Network Star" contestant Katie Cavuto Boyle of Healthy Bites Catering, and Your Humble Narrator were among those joining the former "Partridge Family" star in judging the contest. The Pirassununga 51 Cachaca Triple Orange Caipirinha and the Absolut Mango Tango were judges' choice and guests' choice winners.

* Speaking of Bonaduce, he just appeared on the season premiere of DUTV's "In Bed with Butch." Bonaduce and host Butch Cordora taped the interview in the bed of Bonaduce and Railsback's Old City condo. The guys wore smoking jackets and talked about steroids, anger-managment issues and infidelity, of which Bonaduce is familiar.

Pink's mom is very proud

Pink's mom Judy wore a red cape with "I'm the Mom" ironed onto it to her daughter's sold-out show at the Wachovia Center Saturday night, according to her daughter's Twitter post. Pink, aka Doylestown native Alecia Moore, showed no signs of her recent shoulder injury as she descended to the stage on a circus rope and stayed in constant motion throughout her lengthy set.

Out and about

* "Extra" host Mario Lopez celebrated his 36th birthday, which is Saturday, with a party at the Borgata's mur.mur nightclub Saturday. Lopez and new girlfriend, actress Courtney Mazza, stayed in a Water Club suite and dined at Izakaya before his party, where DJ Samantha Ronson spun as her fashion-designer sister Charlotte hung out with her in the booth. mur.mur girls gave Lopez a cake with a picture on it of him shirtless on a beach. Also at Borgata, Blink 182 partied in MIXX with opening act Asher Roth following their show in the Event Center. Blink's Mark Hoppus and Tom DeLonge dined at Izakaya.

* "Dancing with the Stars" alums Gilles Marini and Shannon Elizabeth, and current cast member Aaron Carter, were all at Dusk inside Caesars in Atlantic City Friday night.

Singer Carter, not known for any nudity, sipped Ketel One and soda.

* Phillies reliever Jamie Moyer and wife Karen at Saloon (750 S. 7th) for dinner after Thursday's loss to the Houston Astros.
