You Have To See This '70s Throwback Pic Of Kourtney Kardashian And Her Parents

We've got disco fever.

Kourtney Kardashian got the jump on everyone else’s #ThrowbackThursday with two epic ‘70s era baby pics.

The “Keeping Up With the Kardashians” star took to Instagram Tuesday (Mar. 31) to post photos from 1979 of her late father, Robert Kardashian, and her mother, Kris, cradling baby Kourtney.

The 35-year old mother of three is the cutest baby ever in the pics, while her mother sports a beautiful yellow sundress. Her dad, however, with his bushy ‘stache, sunglasses, unbuttoned shirt and gold chain looks as though he’d give “Saturday Night Fever”-era John Travolta a run for his money boogie oogie oogie-ing at the local discotheque.

“Me and my ultra chic parents. @krisjenner where is this dress? I need it,” she wrote.

Excuse us, now we've got disco fever.

“Keeping Up With the Kardashians” airs on E! on Sundays at 9/8c.
