Katharine Towne (“The Bachelor”), Lauren Graham (“Conrad Bloom”) and newcomer Colin Mortensen (MTV’s “The Real World: Hawaii”) have been cast in the NBC midseason laffer “M.Y.O.B.”

The series, from exec producer Don Roos (“The Opposite of Sex,” “Single White Female”), revolves around a teen runaway (Towne) whose search for her birth mother results in a new relationship with a snooty aunt (Graham) who works at a high school. Mortensen will play a not-so-bright office assistant, while newcomer Paul Fitzgerald will play an assistant principal.

Roos and Ann Donahue (“Murder One”) are exec producers of “M.Y.O.B.,” which is being produced by NBC Studios. Peacock is expected to bow the skein early next year.
