So much for staying Friends...
“Matt is in for a rude awakening,” spills the source, who says Perry, 52, is going to take the Top Gear host, 54, to task over his decision to launch his spinoff series, Joey, right after their sitcom ended its 10-season run in 2004.
"The full story of that betrayal hasn’t been told yet, and Matthew is not going to pull any punches,” the source says, adding that Perry plans to be "very frank" about his take on the spinoff.
“It’s been 18 years, but the Joey thing still stings Matthew and the other cast members because it was the only time one of them went behind everybody else’s back and tried to break up the act,” the source explains. “Matthew didn’t bring it up on the reunion last year, but he’s ready to set the record straight and isn’t going to hold back.”
As OK! previously reported, Perry has the rest of his former cast mates "in a panic" over his looming memoir release, as he is expected to "unload on the whole crew."
The actor — who has long battled addictions to alcohol and painkillers — "figures it's time to come clean not just about his own life, but also about the good, the bad and the ugly things that happened on the Friends set."
"He really couldn't care less" about upsetting the rest of the cast members, insisted the source, who confirmed: "He's not going to hold back."
"He didn't feel like any of them supported him, and it was a bitter reminder of how much he suffered back when they were shooting the show," the insider continued. "They weren't as close as people think. Their characters were so tight, but the reality is there was a lot of tension and jealousy."
