The 47-year-old singer has decided to wave goodbye to his fairly luscious thick black hair after his wife, Ayda, 42, decided to give him an impromptu haircut at their family home.
You can see his new look below:
Posting a video on her Instagram, mum-of-four Ayda says to the camera: "It's about to happen," as she brandishes clippers.
The pair sat on the balcony of their home as Ayda showed absolutely no mercy in shaving Robbie's hair off - even blowing a few stray strands into his face.
She then captioned the video: "Robbie Williams is all or nothing when it comes to his hair ...and apparently, it's nothing now."
Ayda then jokingly added the hashtags 'no hair don't care' and 'the bald and the beautiful.'
Well, it's certainly a stark change.
Fans seemed to love Robbie's new bald bonce, with many saying it wiped years off the star.
"He looks so much younger now!" gushed one comment, while a second added: "Ah, he's like 90's Robbie all over again."
"It took years off him," a third said. "He looks amazing with or without it."
Former Take That star Robbie moved to Los Angeles in 2006, and still spends most of this time Stateside with his family.
He initially moved to America after his time in Take That and his solo career made him a household name in the UK.
However, he has since spoken out about having 'regrets' for not cracking the US, having turned down a number of lucrative offers at the time.
Speaking on The Johnathan Ross Show, Robbie explained: "I just thought I'm not going to promote anything, go live there and be anonymous and enjoy the spoils of what I've achieved.
"What else do I want? I got offered nice things and turned them down."
"Now I'm older, I'm like: 'I should have done that.'"
Weren't you the one who sung about having No Regrets, Robbie?
