The 'Keeping Up with the Kardashian' star met her sister Kim Kardashian West and Kanye West's new baby for the first time over the weekend and she is already besotted with tiny tot and couldn't help but brag about his sweet features when she sat down for a live stream with her fans on her website last night (07.12.15).

She said in the short black-and-white video clip: "My little nephew was born he is so cute and so perfect. I love him and mommy and daddy are doing fantastic."

And, although the blonde beauty was thrilled to meet the little one for the first time, she has admitted she was struck with mixed emotions when she stepped into Cedars-Sinai hospital in Los Angeles, where Saint was born, to visit the new bundle of joy as she's spent the last three months dashing back and forth to the medical centre to visit her estranged husband Lamar Odom following his collapse.

She took to her Twitter account over the weekend and tweeted to her fans: "I know these hospital halls way too well. Hopping from one room to another."

Kim and Kanye - who already have two-year-old daughter North together - announced the arrival of their baby son via a joint statement on the reality TV star's website.

However, Saint's birth wasn't easy for Kim as she reportedly suffered from placenta accreta, where the placenta remains attached to the womb, and was forced to deliver him three weeks ahead of her due date on Christmas Day (25.12.15).
