Kylie Jenner sends adorable message to Khloe Kardashian after birth of her baby

Kylie Jenner has become the latest member of the Kardashian/Jenner family to congratulate Khloe on the birth of her baby.

Taking to Snapchat (very generation Z), she posted an adorable Snapchat filter saying: “Kongrats, Khloe! It’s a girl”.

Kris Jenner officially announced the pregnancy last night, writing alongside a video of Kendall Jenner repeatedly saying ‘baby’: "BLESSED!!! #Repost @wmag ・・・.

"When three of your sisters give birth in under a year. Congratulations to @KhloeKardashian on welcoming another girl to the KarJenner clan."

Khloe gave birth following a week of reports that her boyfriend Tristan Thompson had cheated on her with multiple women - and was filmed seemingly kissing a woman in a New York nightclub.

The footage, obtained by the Daily Mail, appears to show Tristan getting close with the woman - though it isn't clear in the film if they are actually kissing.

But the woman who filmed the clip told the publication: "I was there and he was on the table right next to us with a group of friends and some girl who he was obviously making out with all night.

"They were holding each other and it was so obvious. They were there when I got there and they were part of a big group of friends.

"They were talking and being around each other all night. He was texting and talking on the phone and she was obviously looking over his shoulder."

TMZ subsequently released another clip of Tristan getting cosy with two more women back in October.
