The athlete showed off her insanely bright new do while out on the golf course with doing a spot of caddieing for fiancé Rory McIlroy on Wednesday (9 April).
Well, at least there's no chance of Rory losing her on the green!
Caroline had hinted at an image change back on 2 April when she tweeted: "Does anyone know if semi permanent hair dye from brand Manic Panic washes off completely after a little while?"
Manic Panic describes itself as "extremist" and "electrifying" colour so, judging from Caroline's locks, we reckon she definitely went for it!
Her eye-catching barnet almost – almost – distracted us from the gorgeous engagement ring she's been sporting since Rory proposed over the New Year.
Caroline joked to BBC: "Rory did really well. How could I say no with that ring?! It was a surprise!"
As for wedding plans, Rory said: "We're working on it. Obviously we're very busy and concentrating on other things. When the time is right we'll get around to it."
Is the big day soon? "You never know," is all Caroline would say.
Caroline was serving as Rory's caddie during the pre-Master Par 3 contest at Augusta National Golf Club. It's the second year in a row she's done it.
