Can you guess who this Hollywood actress is?

She started her career on 90s TV shows like Hey Dad..! and Brides of Christ, before becoming one of Australia’s most successful actresses in Hollywood.

The 48-year-old star, however, looked unrecognisable in throwback photos from her days on Bride of Christ.

But the fresh-faced 20-something year old is none other than Naomi Watts.

The mother-of-two starred alongside actress Kym Wilson and Melissa Thomas on the show about catholic school life.

After the show ended, Naomi would go on to star in blockbuster Hollywood films such as The Ring King Kong, and Mulholland Drive.
