Khloe Kardashian has never been happier

Speaking on 'Keeping Up With the Kardashians' in an episode which aired on Sunday (12.11.17), Khloe - who was previously married to Lamar Odom - said: "I've never had a surprise party ever.

"We were at dinner and Tristan was so calm. He was as cool as a cucumber. He's good at surprise parties because I had no clue...

"Tristan is just incredible. I've never been this happy. I am so lucky to be with someone that is so thoughtful and so sweet."

The NBA star is keen to be seen as a "part of the family" by Khloe's loved ones, and she was delighted that he wanted to spend the summer in Los Angeles to get to know them better.

Khloe told her sisters: "I love that Tristan was like, 'I want to be there this summer.'

"We're always in Cleveland. He literally can't [wait to] come here and hang out with you guys. He's like, 'I want to be a part of your family and do stuff as a group.'

"He was like, 'I want to be with your family more,' and he really wants to hang out with all of us more. We're going to be here, but we also want a house in the city."

The 'Revenge Body' star wanted to find a rental property in Los Angeles for the summer so the 26-year-old Cleveland Cavaliers player could be closer to his training facilities at UCLA, but ultimately decided it was better for him to move into her own "beautiful home".

She said: "After talking with Tristan we have come to the conclusion that I'm crazy.

"I don't know why I was stressing myself out when we have our beautiful home in Calabasas. All Tristan really wants is to be with me and for us to enjoy our summer together. That's really all that matters."
