Diane Farr

Tough but sexy, Farr has spent most of her career in the company of men. She provided a women's perspective on MTV's relationship chat fest Lovelines before making the leap to acting with recurring roles on The Drew Carey Show and Roswell. Farr got her big break in a pair of Denis Leary series: as the lone girl detective on the short-lived dramedy The Job and as the sole female firefighter on Rescue Me. Although the latter was a hit, Farr traded flames for gunfire as the only female FBI agent on Numbers. Off screen, she enjoys a concurrent career as a writer and entrepreneur. In addition to contributing articles to a number of magazines, she published her first novel, The Girl Code: The Secret Language of Single Women, in 2001. The good-natured guy's gal also turned a potentially devastating breakup with her ex-fiancé into a business, launching the comedic card company OtherAnnouncements.com after sending out a homemade card stating that she was single again.
