Los Angeles: Actress Sarah Chalke will star opposite Rob Riggle on Fox' comedy pilot ''48 Hours 'Til Monday'.
Chalke, 38, will play Kelly Bishop, happily married to Charlie (Rob Riggle) and the mother of their three kids: Elizabeth, George and Mac, said the Hollywood Reporter.
A strong, excitable beauty, Kelly quit her job as a local TV news producer to spend more time with her family and is finding that being a stay-at-home mom is much more exhausting, time-consuming and frustrating than working in an office.
The role marks Chalke's latest comedy foray following 'Scrubs', 'How to Live With Your Parents' and 'How I Met Your Mother'.
She joins a cast that also includes Jane Curtin as Louise, Kelly's wry and fun mom; and 'Once Upon a Time' actress Merrin Dungey as Candace, Kelly's rival-turned-friend.
