Kim Kardashian West has been having "sympathy cravings".
The 37-year-old reality star - who has daughter North, four, and son Saint, 22 months, with husband Kanye West - is expecting her third child via a surrogate but has been experiencing some of the symptoms she had while carrying her other children.
A source said: "It's so weird - Kim can't believe it. Kim had a week of feeling so fatigued, just like when she was pregnant with North and Saint.
"She spoke to the surrogate, who said she'd been feeling the same.
"Kim was also obsessed with a Parisian cheesecake when she was pregnant, and she had her chef perfect the recipe. She's been craving it so much again lately.
"Kim says she feels very connected to the baby and is always checking in with the surrogate so she reckons it's no wonder she's getting sympathy cravings."
But the 'Keeping Up With the Kardashians' star is unlikely to be giving in to her cravings as she's determined to be in better shape than ever when the baby arrives.
A source told heat magazine: "She's never been as motivated. She's been on a diet of 700 calories a day for months now.
"She wants to be model skinny and her goal is to get down to [98lbs]."
Kim was advised by doctors not to get pregnant again because of medical complications, but she's also previously admitted she found it hard to see her body change.
She said: "My body just went crazy. After five months, I swore I'd never get pregnant again. It felt like someone had taken over my body."
And in another interview, she admitted: "I gained a lot of weight. It was really hard mentally."
