This week, three fan-favorites have announced they are leaving CNN.

With the announced CNN Newsroom anchor shakeup, it left Heidi Collins without an anchoring spot. She will be leaving CNN on Friday, January 15th. After joining CNN Worldwide seven years ago as a news anchor for what was then CNN Headline News, she has become a news anchor for American Morning, The Situation Room, Anderson Cooper 360° and CNN Newsroom. No further information has been announced about her future plans.

Abbi Tatton's last broadcast on The Situation Room with Wolf Blitzer was today. Abbi has been with the Washington DC bureau of CNN since 2000, working as a political producer/production coordinator for CNN Election Express and a producer for such shows as Inside Politics, Crossfire and On The Story.

On Tonight's Anderson Cooper 360°, Anderson announced that Erica is "moving on to an exciting future at CBS News." Hill began filling in on the weekend edition of the CBS Early Show in August 2008, and was named a co-anchor in September 2008. She joined CNN Worldwide in January 2003 as an anchor for then - Headline News, then moving to host Prime News with Erica Hill before leaving Atlanta to join Anderson Cooper 360° in New York in February 2008.

We wish them all the best.
