According to The Hollywood Reporter, Garth and the "My Best Friend's Girl" cast had a table read on Monday (April 14) and they reached a mutual agreement to part ways.
Producers have moved quickly to cast Kristin Booth as the new female lead.
"My Best Friend's Girl" focuses on a pair of best friends whose bromance becomes complicated when one guy (Tim Peper) starts dating his buddy's (Josh Cooke) ex-wife (Booth).
The show's producers obviously had a type, because Booth is a dead-ringer for a slightly younger Jennie Garth. Her credits include TNT's "The Company," an episode of "Supernatural" and a ton of Canadian TV.
But what of Garth?
There have been widespread reports that the "Beverly Hill, 90210" spinoff's original scribe, Rob Thomas, was hoping to have Garth return as Kelly Taylor in a move that would create continuity between the two shows. Thomas, busy with two ABC pilots, has stepped out of his role as driving creative force on The CW pilot and it's unclear what new showrunners/scribes Gabe Sachs and Jeff Judah would have in mind.
