Jenna said: "I have a nine-year-old, she did not have a party like this. Because, y'all, this party was over the top!"
The mom-of-three didn't hold back as she expressed her disbelief at the billionaire's antics, but then insisted: "Believe me, I love Kim Kardashian, so nothing against her."
Jenna admitted that while she had "many of her own birthdays" as she grew up in The White House, there had never been one as extravagant as this.

Her stand-in co-host, Michelle Buteau, agreed and said the trip - which reportedly cost $150million - was "extravagant upon extravagant".
Viewers were surprised by the criticism, given that Jenna is fond of Kim. Comments on social media began springing up with some agreeing with Jenna but others insisting as long as the kids had fun, that was all that mattered.
Those watching the segment were likely a little on edge, wondering if Kim would respond in any way.

The weekend was dubbed Camp North and Kim had gone all out with the decor too adding helium balloons and many spooky Halloween decorations too.
