The Whole Truthis taking aim at cougars.
"She's fabulous," executive producer Tom Donaghy says. "She just signed on to do [an episode called] 'When Cougars Attack,' in which a high-fashion designer is accused of murdering her young lover."
Judd Hirsch, who co-starred with Truth's leading man Rob Morrow in Numb3rs, was the first to sign on to guest-star, but Donaghy hopes the pair won't be the last. "I want to cast all my famous friends," he says with a laugh.
The Whole Truth debuts Wednesday, Sept. 22 at 10/9c on ABC.
