As an American Idol alum and a talk show regular, Pickler is no stranger to the small screen. But her acting debut in an upcoming episode of the CW's 90210 was "a blast," the singer Tweeted after filming. "So exciting!!!"
Of course, Pickler's role wasn't too much of a stretch – she plays Sally, the country singer cousin of newcomer Justin Deeley's character, Austin. In the episode, Sally sings Pickler's newest single, "Tough," during a talent show to raise money for cancer treatment for Raj (played by Manish Dayal).
"Everyone was so welcoming," Pickler told PEOPLE of the experience. "I enjoyed stepping out of my comfort zone and I'd love to do it again, but at the end of the day, I want to be on the radio."
The 90210 episode featuring Pickler airs Oct. 18. The country star-power continues later in the season when Billy Ray Cyrus does a guest spot as Austin's dad.
