Kelly Ripa is still “pretty pissed off” about Michael Strahan’s Tuesday announcement that he was departing Live! With Kelly and Michael to go full-time at Good Morning America, according to a source on the set of the daytime talk show.

Ripa skipped Wednesday’s taping of the show after Strahan revealed that he’d be leaving, and the source told ET that the 45-year-old co-host has “threatened to not come back until Michael leaves,” adding that the production staff is still unsure of her status for the rest of the week.

Variety’s Debra Birnbaum reported on Wednesday that ABC said Ripa will not return until “next Tuesday at the earliest.”

ET’s source went on to say that Ripa was blindsided by the news of her Strahan's departure, and feels “betrayed,” as she is also not happy on Live!.

“She put her neck out for Michael to be a part of the show four years ago,” the source added. “She is actually miserable with the show, has been for a while now...They have not [been] getting along that well recently, but this [takes] the cake.”
