Kris Jenner definitely has something big to smile about today!

Sep 23, 2014

It's a big week for Kardashian mama Kris Jenner!

The Keeping Up With the Kardashians star finally filed for divorce from Bruce Jenner yesterday, and if the picture above is anything to go by, she is over the moon. Kris was pictured smiling widely as she walked through LAX to board her flight to Europe.

No doubt the beginning of official divorce proceedings is a relief for the couple, who have been separated since June 2013 – though no public announcement was made until October 2013.

Kris reportedly cited "irreconcilable differences" as the reason for divorce, and she is filing "pro per" which means she won't be using a lawyer. The couple had no prenuptial agreement and have already decided how their property will be split, so it sounds like things will go smoothly from here on out. They will also share joint custody of Kylie – their only child under 18 years of age.

Bruce and Kris tied the knot in 1991 – and honeymooned in Ireland, who knew?! They were married for 22 years before splitting, saying they were "happier this way."

If this news has you feeling a little nostalgic, here's a couple of throwback pics to really get you going!

We love this adorable snap of the pair with Kylie and Kendall at a movie premiere in 2003…
