Kourtney Kardashian's mood swings "scare" her boyfriend.
The pregnant 30-year-old reality TV star - who is expecting her first child with partner Scott Disick - admits her hormones are affecting her temperament but she is doing her best to try not to be rude to those close to her.
She said: "Scott keeps getting scared, but he's been great with my mood swings so far. He's like, 'Just take a deep breath.' He heard that with the last three months of a pregnancy you have really extreme mood swings so he was joking, 'Oh, you're not going to believe the mood swings'."
It's not just Disick who has been getting the sharp end of Kourtney's tongue, her family - including sisters Kim and Khloe and mother Kris - have also been suffering.
Kardashian explained to People magazine: "If I'm just trying to pick a fight with someone and if I'm around Scott or my mom, then they'll probably get it worst. If someone is annoying me - usually my mom - I'll call Khloe and it'll make me feel better because she'll agree with me."
Kardashian has previously admitted the pregnancy has changed her personality, revealing she can't help picking on Disick.
She said "I throw b***h fits. The other day, I was like, 'This house is such a mess. Now that Scott's living in my house, there's stuff everywhere. We need to get it organised' Everything I had to do, I blamed it on Scott."
Kardashian is due to give birth in December , and does not yet know the sex of the baby.
She initially wasn't sure if she wanted to be told the gender, but is now looking forward to finding out.
The star said: "I'm starting to get presents from people, and really, how many yellow outfits do I need?"
