Castroneves dance partner to sing national anthem at Indy 500

Julianne Hough, a two-time winner of Dancing with the Stars, will sing the national anthem at this year's Indianapolis 500. Hough won last season's competition with Helio Castroneves, a two-time Indy 500 winning driver. Hough also plans to sing some songs from her debut country album, which will be released May 20. She is scheduled to tour this summer with country star Brad Paisley.

"I've never been to the race, and it will give me a chance to cheer on my friend and dancing partner, Helio Castroneves," Hough said in a statement Tuesday. The 19-year-old has been dancing and pursuing a singing career.
