Kim's nephew was against North's b'day bash at his home

Kim Kardashian says that her nephew Mason was not in favour of her having a Coachella-themed birthday bash for her daughter North at his home.

Kim hosted her daughter's first birthday bash in the back garden of Kourtney and Scott Disick's home in Calabasas.

"When I said, 'North's having a birthday party at your house,' Mason said, 'No! I'm having a birthday party at my house! She can never have a party!" Kim told people.com.

Kourtney said: "Before Kim even said we were having it at his house, he said, 'I'm going to put Legos everywhere! I'm going to scare everybody!'"

The youngest of the Kardashian sisters, Khloe doesn't believe Mason is jealous of North, but thinks he takes after his "moody" mum.

"He's very moody. He's very Kourtney-like. If he wants to do something he will. If he doesn't, you can't get him to do anything," she said.

Kourtney begs to differ and remains adamant that Mason's temperament comes from his father Scott Disick.

"He might be a little more Scott's personality than mine. He's just the life of the party," she said.
