The 26-year-old singer shared several photos of her new look on Twitter before watching the Los Angeles Clippers battle the Oklahoma City Thunder NBA in a playoff game in Los Angeles.
The singer's new look seems to have been inspired by Nicky Minaj's ever-changing hair color.
"We raided Nicki's wig closet for the summer! Bad gals just wanna have fun!" Rihanna captioned another photo where she appears with a friend identified only as Melissa.
Rihanna's latest NBA outing comes days after the "We Found Love" singer donated $25,000 to the the Los Angeles Police Foundation following an incident in which she accidentally broke LA Police Commission President Steve Soboroff's cell phone at another Clippers NBA playoff game on Friday, May 9.
