Nothing against the Boston gala emcees, but here’s one party host who might actually move some tickets. We hear that Bravo TV executive and funnyman Andy Cohen will host the eighth annual Lenny Zakim Fund Casino Night at the Four Seasons Hotel on March 4. Cohen is not just the brains behind “Watch What Happens Live” and any number of “Real Housewives” reunion slugfests. He’s also author of the bestseller “Superficial: More Adventures From the Andy Cohen Diaries” and a Boston University grad (with a degree in broadcast journalism, not surprisingly). The bash will be co-chaired by Burn Later Productions cofounder Sam Slater, Boston City Councilor Josh Zakim, and philanthropist Amy Belkin Mofenson. The Lenny Zakim Fund supports grass-roots social justice organizations throughout Eastern Massachusetts.
