SARAH MICHELLE GELLAR is enjoying a lovefest with her new TV co-star Robin Williams, but the relationship is rubbing SMG's hubby Freddie Prinze Jr. the WRONG WAY, say insiders.
Williams, 62, is returning to his first full-time TV gig since his career-making sitcom “Mork & Mindy.” He’ll be teaming with 36-year-old Gellar in the CBS comedy “The Crazy Ones,” premiering Sept. 26.
The pair play the father-and-daughter heads of a big-time advertising firm, and Gellar says they are just as close in real life.
“I actually applied for Robin Williams to adopt me,” she quipped.
That’s apparently the kind of thing her hubby of 11 years doesn’t want to hear. And Oscar winner Williams – a married dad of three grown kids – accidentally made matters worse when Prinze, 37, recently visited the set.
