When we heard that Mekia Cox had been cast to replace Jessica Parker Kennedy in NBC's buzzed-about new series, "Undercovers," we felt we knew her from somewhere... and we did. She played Sasha, Dixon's older, crazy girlfriend last season on "90210."

Dixon probably thought he was rid of her after finding out that she was faking her pregnancy and he kicked her to the curb, but now Zap2it exclusively learns that Sasha and all her crazy will be back. 

A CW spokesperson confirms that Cox will reprise her role as Sasha in Season 3 and she'll be rocking Dixon's ( Tristan Wilds) world. 

When we last saw the deejay, Sasha donned those pretty loud eighties-inspired shirts and big earrings. When we see her next in the episode airing October 4, Sasha will have taken on a more sophisticated look and she's back to deliver some shocking news to Dixon. 

What wrench do you think Sasha will throw into Dixon's story line?
