Uinterview - u ask. they tell.

Kellie Pickler's bubbly personality and country twang have carried her far from her early days on American Idol. With two studio albums under her belt and a third on its way, Pickler continues to cash in — and now she's branching out into acting. She guest-stars on the October 18 episode of the CW's 90210, on which she will perform her single "Tough."

She will play the role of Sally, the cousin of country singer Austin, a new hottie on the show played by Justin Deeley. Pickler, who grew up in small town North Carolina, joked that she had to stretch her acting muscles to fill in the role. "My zip code growing up was a long way from 90210, so it will definitely be acting," she told TheBoot.com. "I'm really excited and a little bit nervous about it, but it will be a fun and unique place to perform 'Tough.'"
