Kim Kardashian held Khloe's leg as she gave birth, refuses to mention Tristan Thompson

Kim Kardashian has taken to social media to celebrate her sister, Khloe, giving birth, but made no mention of the baby's father, Tristan Thompson.

In the days leading up to welcoming the baby, he was accused of cheating with multiple women in stories published with video purporting to show him in the act.

Kim shared with fans her story about being with Khloe when she was in labour and even holding her leg, but refused to mention Tristan.

"Khloe I'm so happy for you! Your baby girl is so beautiful," gushed Kim.

"You are so strong. You made that look so easy! I can't wait for our baby girls to grow up as best friends the way we are! I'm so happy I was able to return the favour of holding your leg while you pushed."

The Kardashians have yet to officially respond to the stories of Tristan's infidelity, but are reportedly planning a "co-ordinated attack" on him.

Khloe finding out about his alleged mistresses and her having the baby are expected to be documented in reality TV show Keeping Up with the Kardashians.
