I know, only three years, didn't it seem soooo much longer? You know, with her dating Harry Styles and everything.... After an indeterminable amount of time (allegedly 3 years) Caroline Flack has officially hung up her formal shorts and 'quit' the Xtra Factor. She will be replaced by some lady from Radio 1 by the name of Sarah Jane Crawford.

Flack made her "lil announcement" via Instagram last night...

Caroline's former co-host Olly Murs (recently most famed for being tackled from behind by a certain Jose over the weekend) was quick to post a *dances* MONTAGE of their happy times hosting the show back in 2011.
