Jessica Chaffin (Spy) and Telenovela‘s Diana Maria Riva have been cast opposite Matt LeBlanc in CBS’ untitled LeBlanc/Filgos comedy pilot (aka I’m Not Your Friend).

Written on spec by Jeff & Jackie Filgos and to be directed by James Burrows, the multi-camera comedy stars LeBlanc as Adam, a contractor, who agrees to take over parenting chores when his wife Andi (Jenna Fischer) goes back to work. As he starts spending more time with his kids, he discovers the truth every parent eventually realizes: his little angels are maniacs.

Chaffin will play Marie, a frazzled mom who is disgruntled to learn that Adam (LeBlanc) doesn’t remember her — after meeting her a half dozen times. Riva is Mrs. Wannamaker, the lead teacher at the school who appears cozy and matronly but is a storm trooper who runs a very tight ship.

Chaffin, repped by CAA, MGMT Entertainment and attorney Jeff Endlich, recently appeared on Mike & Molly, You’re The Worst and recurred on Episodes. Riva plays Mimi Moncada on NBC’s Telenovela. She’s repped by The Kohner Agency, Gateway Management and attorney Bob Myman.
