Bianca de la Garza hosted a party on the patio at Fairmont Battery Wharf Thursday to benefit the Zack Heger Foundation for Duchenne Muscular Dystrophy. Heger, who lives in Westwood, was there, along with some of the WCVB-TV anchor’s friends and colleagues, including Susan Wornick, Randy Price, Pats coach Bill Belichick and girlfriend Linda Holliday, “Accidental Billionaires” author Ben Mezrich and wife Tonya, fashionista Marilyn Riseman, Celts CEO Wyc Grousbeck and wife Corinne, “Greater Boston” host Emily Rooney, and comedian Steve Sweeney. . . . Somebody who attended this week’s LifeSavor gala at the Langham Hotel benefiting Community Servings must really like Andy Cohen. A chance to meet the Bravo host and be present for a taping of “Watch What Happens Live” was part of a package that fetched $5,300 at auction. The anonymous bidder also gets to have lunch with Michael Lorber of “Million Dollar Listing” at Cipriani and gets a two-night stay at OUT Hotel in New York.
