Britney Spears has added a new opening act. Ciara and Kristinia DeBarge will join Ms. Spears on the North American second leg of Britney Spears' Circus Tour.

Kristinia said,

"Joining Britney Spears for her Circus tour will be an amazing and surreal experience for me. I have been dreaming of an opportunity like this forever, and can't wait."

Ms DeBarge is the daughter of 80's pop star James DeBarge. Her current single "Goodbye" is available on iTunes.

Britney's tour kicks off August 20 in Hamilton, Ontario.
