GMA CHEATER'S WIFE EXPLODES!

GOOD Morning America anchor T.J. Holmes’ betrayed wife is lashing out at both her horndog hubby and her former bestie Amy Robach for shamelessly flaunting their sordid affair in public!

In a stinging public explosion, Marilee Fiebig says she’s “disappointed by T.J’s lack of discretion, respect and sensitivity” after sizzling images emerged of her estranged 45-year-old husband locking lips with his hot-to-trot honey Robach, 49, during a holiday getaway to Miami.

“It must have been like a gut punch for Marilee,” notes an insider. “First she’s betrayed and humiliated by T.J. and Amy when the affair was revealed, and now she’s forced to watch them carrying on like lovestruck teenagers who can’t keep their hands to themselves.
