Big weekend for celebrity weddings — from coast-to-coast

Newlyweds Helen Lasichanh and Pharrell Williams

Saturday was the date tapped by several celebs to walk down the aisle. Grammy winner Pharrell Williams tied the knot with his longtime girlfriend, model Helen Lasichanh in Miami, the mother of son Rocket, 4. The happy couple also were treated to a special mini-concert at their nuptials — staged by good friends Usher and Busta Rhymes.

†Also marrying Saturday were rocker Matt Sorum and singer/dancer Adriane “Ace” Harper. The ex-Guns N’ Roses and Velvet Revolver drummer and his lady love exchanged their vows in Palm Springs — toasted by a guest list that included Steven Tyler, Juliette Lewis, Jane Lynch, John Stamos, Dave Navarro, designer John Varvatos and Sorum’s former Guns N’ Roses bandmates Slash and Duff McKagan.

†On the East Coast “Mad Man” actor Ben Feldman married his fiancée Michelle Mulitz at a Gaithersburg, Maryland farm — joined by a guest list that included CNN’s Wolf Blitzer, “Veep” star Reid Scott and Tony winner Patina Miller.

†Back out in Malibu, Calif., “The Hills” reality TV star Jason Wahler married Ashley Black, invoking Dr. Seuss in his vows, which he shared with Life & Style magazine. “Dr. Seuss once said you know you’re in love when reality is better than your dreams.” Wahler, who once dated both of his “The Hills” co-stars Lauren Conrad and Kristin Cavallari (now married to Jay Cutler), has maintained three years of sobriety after participating in VH1’s “Celebrity Rehab with Dr. Drew” in 2010. Dr. Drew Pinsky himself was among the guests at the wedding, joined by Janice Dickinson, Andy Milonakis, and “Laguna Beach’s” Cedric Channels.
