Osbourne's new look debuted on celebrity hair colorist Jack Martin's Instagram page and people are already obsessed.
According to Martin's post, the talk show host had been coloring her hair red for 18 year and was ready for a change.
"It took me a total of 8 hours from start to finish to get her to a platinum blonde so she doesn’t have to be committed to coloring her hair once a week anymore," Martin writes.
It seems like people are loving Osbourne's new look as Martin's Instagram post garnered over 50,000 likes in less than 24 hours.
Osbourne joins a growing list of people embracing a more natural look including celebs like Jane Fonda and Sylvester Stallone.
