KRIS JENNER BEATS HER DAUGHTER KYLIE IN A FAMILY SWIM SUIT CONTEST.

Kris Jenner wore it best! Khloe Kardashian took it upon herself to do an official poll amongst her famous family, to decide whether her mom or her little sister Kylie Jenner wore their hot pink '80s swimsuit better.mobile.twitter.com/khloekardashian

As  previously reported , momager Kris took to Twitter on Thursday, Aug. 13, to reveal that her sneaky daughter Kylie had stolen her swimsuit for her Mexican birthday trip.

"Ohhhhhhh so THIS is where my vintage Body Glove bathing suit went!!!!" Kris, 59, began her note, which captioned side-by-side photos of the ladies in the eye-popping one-piece. "@kyliejenner you are grounded! Wait, I can't do that anymore you're 18…"

Kris went on to ask followers "#whoworeitbetter," and it seems Khloe couldn't resist finding out the official answer, by launching a family-wide poll.

All members of the reality TV gang got involved with the answer. Kylie voted for herself, while Kim sided with her mom ("Sorry Kyles mom wins!" she wrote).

The contest even drew usually reclusive Rob Kardashian out of his shell, with Kylie's 28-year-old half-brother also siding with the famous matriarch.

The Kardashian result mirrors the results of Us Weekly's online poll! At the time of publication, Kris is beating Kylie by 90 percent to 10.
