Khloe Kardashian "spends more time" at boyfriend Tristan Thompson’s house in Cleveland, Ohio than at home in Los Angeles.
The ‘Revenge Body’ star has only been dating the Cleveland Cavaliers player since last September, but things appear to be hotting up between the couple as the blonde beauty is never home.
A source told PEOPLE magazine: "Khloe says things are serious.
"She spends more time with Tristan in Cleveland than in Los Angeles."
Earlier this month, the 32-year-old reality star opened up about how "serious" things are getting between them while appearing on ‘The Late Late Show with James Corden’.
The British comedian said to her: "I feel like I’m spotting something different about you – this time you might be glowing!
"You seem like somebody who may have found love recently?"
The smiling star replied: "I have! I am, I’m very happy.
"It’s going good We use the L word!"
When James, 38, then asked his guest how long she and James "have been French kissing", she laughed and said: "A little bit now/ We just started French kissing. That’s when it’s serious!"
The ‘Keeping Up With the Kardashians’ star also praised her 25-year-old boyfriend as "pretty awesome" during an interview on ‘Today’.
She said: "Tristan is pretty awesome. You’re making me blush!"
Khloe – who was previously married to Lamar Odom – then joked about numerous rumours speculating she was pregnant over the years, but admitted she does want a family of her own one day.
She said: "I’ve been pregnant for about eight years now — I’m pregnant with triplets at this point …
"I hope so. I definitely hope so! I mean, God willing."
Earlier this month, Khloe admitted she is the happiest she’s been for a long time thanks to her relationship.
She said: "At this moment, a few days into 2017, I feel incredibly clear and probably the happiest I’ve been in years. It’s such a great feeling that I have my happy back!
"It’s from a genuine place and the most peaceful place I’ve been in for longer than I can even remember … I think when you’re in love you definitely feel happy and healthy too. I like that my relationship is very normal and doesn’t need to be so publicised all the time."
