Kris Jenner turns 63: See the Kardashian matriarch through the years

You'd think managing six kids would age a woman quickly, but there's no doubt about it: Kris Jenner is looking sexy at 63.

The Kardashian family matriarch is celebrating a birthday today, and her kids certainly aren't letting the occasion go by unnoticed.

"Happy birthday beautiful mommy!! You make life look fabulous! At every single stage!" Khloe Kardashian gushed on Instagram in a lengthy tribute to her mother, adding, "Today please enjoy being the Queen that you are!!!"

See Kris Jenner in the 1990s:

Khloe posted the tribute alongside a photo of Kris cuddling baby True, who was born earlier this year.

In addition to True, Kris has 8 other grandchildren through Kourtney, Kim, Kylie and Rob. (Kendall Jenner, 23, has not waded into the waters of motherhood.)

Last week, 21-year-old Kylie gifted her mother a $250,000 red Ferrari as an early birthday gift -- so she'll certainly be riding in 63 in style.
