Guess who! This Real Housewives of Beverly Hills star surprised fans with an unrecognizable flashback photo on Monday

Dorit Kemsley, 43, surprised her followers with the flashback, which she captioned: 'High school graduation. June 1994. I remember feeling like the world was mine to explore. #25YearsAgo'

Many couldn't help but point out how much she's changed. Her sleek blonde hair was once dark and curly and her face looked decidedly different.

'This doesn't look like you at alllll,' one follower wrote.

'You look like a completely different person,' another chimed in.

Reaction: Dorit's followers were quick to comment on the shot

'Money does wonders,' a third added.

Of course, Dorit's transformation has been a hot topic on the most recent season of The Real Housewives of Beverly Hills.

Her friend turned enemy Lisa Vanderpump made a caustic comment about Dorit having had a 'head transplant.'

But the star, who has two children with husband Paul 'PK' Kemsley, insists she's never had surgery on her face.

When quizzed about Vanderpump's observation by Andy Cohen, Dorit denied ever having surgery on her face.

'I'm very happy to say what I've had done. Because I think it's comical when people say that I've had a facelift and a bunch of surgeries. A little botox and filler...that's all I've ever done on my face,' the Beverly Beach designer insisted.

When asked if she'd had a nose job, she replied: 'No! Makeup can do wonders.'
