Khloé Kardashian has visited her sister Kim in hospital following the birth of her baby boy.
The 'Keeping Up With The Kardashians' star welcomed her second child, a son, today (05.12.15) and her younger sister was on hand to visit the newborn whilst also tending to estranged husband Lamar Odom.
She wrote on Twitter: "I know these hospital halls way too well. Hopping from one room to another."
Kourtney Kardashian also alluded to the birth on social media, tweeting, "Baby's breath," alongside emoticons of a blue heart and a pair of praying hands.
The birth of Kim and Kanye West's son was announced on the 35-year-old television personality's website today (05.12.15).
A statement published on the site read: "Kim Kardashian West and her husband, Kanye West, welcomed the arrival of their son this morning. Mother and son are doing well."
And Kim - who also has daughter North, two, with husband Kanye - previously admitted she is planning to take her time to get her post-baby body back following the arrival of her son.
She wrote: "A few weeks to go and 60 pounds up! I look at other celebrities and Instagram girls who are literally so skinny right after giving birth. How is that possible?!?!
"I mean, I'm focused and I love the challenge of getting my body back and feeling good again, BUT I am going to be a little bit more realistic. I'm not saying anyone is being unhealthy or not doing it the right way, but how do they lose weight and look so good so fast?! (sic)"
