Get the Kleenex out, it's the end of an era people. Yes, Kris Jenner has filed for divorce from Bruce Jenner.

The mother hen of the Kardashian business who separated from Bruce 11 months ago has now officially started proceedings to end their 23 year marriage according to documents filed in Los Angeles which have been obtained by Radar Online.

Kris is said to have cited 'irreconcilable differences' as the reason for their split and has asked for joint physical and legal custody of the couple's two daughters Kendall and Kylie (although they're both basically adults at this stage so we don't know why that's necessary but hey, child support is still money in the bank right Kris?).

The papers state that Kris is requesting to keep all of her own jewellery as well as her assets following the official date of their separation which is noted to be June 1 2013.

At the time of their split Kris released a statement saying: 'We are living separately and we are much happier this way. But we will always have much love and respect for each other. Even though we are separated, we will always remain best friends, and, as always, our family will remain our number one priority. We ended a marriage, but that's not the end of our friendship. I will always love him, but we are no longer a couple in that way.'

Following the split, Bruce - who moved from their home in Calabasas, California to Malibu - is reported to have drastically transformed his image by growing out his hair and is even thought to have had his Adam's apple reduced. Which sounds pretty 'irreconcilable' to us to be fair.
