In the trailer of the American sitcom, Brook, 35, strips naked with her hands protecting her modesty.
"How would I do on the lesbian market? I don't think I've ever been appraised," Brook's character asks her co-stars in the trailer.
Produced by TV show host Ellen DeGeneres, the show will go on air in March this year. The sitcom stars Elisha Cuthbert, Brooke Lyons and Misan Akuya besides Brook.
