This Hollywood mum looks completely unrecognisable in never-before-seen throwback photos!

She's one of the most famous mums in Hollywood, but we never would've guess this was Kristen Mary Houghton... who you now know better as KRIS JENNER!

The then-22-year-old looks fresh-faced and unrecognisable in the modelling shots taken by her former boyfriend Alfred M. Garcia.

The photos, which were taken around California's La Jolla and Mission Bay in 1977, have just been released by New York Times bestselling author Jerry Oppenheimer in his book The Kardashians: An American Drama. 

At the time the momager was working as a junior flight attendant for American Airlines.
