*Rihanna has traded in her brown curls for a bleached blond blow-out.

The 23-year-old singer tweeted a topless photo of herself Thursday night with the message: “#Back2Work 1st Cover of the year!!!! #ELLE.”

While Rihanna has gone blonde hair before — recently sporting a blond pixie wig for an Armani Jeans ad campaign and an angled bob in her “You Da One” video — she told her Twitter followers that she had colored her hair for real this time, saying: “lol! I dyed it for #ELLE…bleach + weave #WERQ.”

Later that night, she was spotted courtside at a basketball game between the Denver Nuggets and the Los Angeles Clippers showing off the new look.
