Jennifer Finnigan played Bridget on Bold and the Beautiful for a few years, winning three Emmys.
She was also recently in Crossing Jordan. The way they wrote her out of Crossing Jordan has left the door open for her to come back if Committed does not fare well. (So, I think we'll see her back on that show REALLY soon.)
She normally does not talk like that. It is VERY annoying to watch her on Committed. She normally talks deeper, slower, and more normal. She ruins the already badly-written character by adding such a nasal-tinged voice.
I think the show sucks... Big time...
