But a source told The New York Post, that tensions between the pair is nothing new, explaining that any chemistry they exhibited was “all for the show.” “They could not stand each other,” the source added. “Whenever they communicated off-camera, it was always through their reps.”

Former NFL player Strahan, who was already doing two days a week at ‘GMA’ was said to have been stressed recently due to his double-gig. “He was having temper tantrums. He’d lose it, yelling at [Ripa] and [‘Live’ executive producer Michael] Gelman,” the source said.

“He acted like he was in a locker room, not a dressing room.” Ripa is said to have only found out that her co-host was leaving shortly before the news was made public. But while Ripa isn't taking the news well, her former co-host Regis Philbin has offered his congratulations to Strahan.

“Years ago I interviewed Michael Strahan on my show, and I asked him what he will do when he leaves the Giants. He said, 'I want your job,' and years later he got it,” Phibin told People. “Now he's moving on to GMA. Next stop could be Washington."
