Rihanna's a rockstar and now she's got the hairdo and Madonna's cone bra to prove it.

RiRi debuted newly dyed and styled fiery red hair as she hit the stage at Spain's Rock in Rio music festival on Friday.

The "Rockstar 101" singer strummed on an air guitar as she channelled vintage Madonna in 50s-style cone bra and high-waisted black pants.

The 22-year-old's flaming new 'do with shaved sides was created by celebrity hairstylist Ursula Stephen, according to popeater.com.

Stephen is no stranger to celebrity mops, having styled the likes of Keyshia Cole, Michelle Williams of "Destiny's Child," and "America's Next Top Model" winner Saleisha Stowers.

Rihanna's vibrant performance was the latest stop on her 62-date "Last Girl on Earth tour."

The tour heads to the U.S. in July and is set to finish in Syracuse on August 28.
