Like many gay men, I worship at the altar of Judith Light, who I got to know a bit this past year when she appeared on Broadway in “Other Desert Cities,” for which she won a Tony. So I feel compelled to keep you informed about her doings. This “Who’s the Boss?” legend is returning to her guesting gig on TV Land’s sitcom “The Exes,” where she plays the over-bearing mother to Kristen Johnston’s divorce lawyer character Holly Brooks. Tomorrow night’s new episode, titled “Sister Act,” also stars Amanda Detmer as Light’s other, more beloved, perfect daughter Jill. It’s an extravaganza of blondes.
