Khloe Kardashian's boyfriend has been experiencing sympathy cravings.

The 'Keeping Up With the Kardashians' star has admitted her partner Tristan Thompson has been ''milking'' her pregnancy ''for all he can'' and has claimed he's had an increased desire to scoff Jamaican grub and stuff bundles of cookies into his mouth since they found out they were expecting their first child together last year.

Speaking on the 'Ellen DeGeneres Show' on Wednesday (03.01.18), she said: ''He's so great just during pregnancy and he makes me more excited too. I'm excited. He's been milking the pregnancy for all he can. It's Mainly Jamaican food, it's just an excuse. He loves chocolate chip cookies. Like bundles of them.''

The 33-year-old beauty announced her pregnancy just before Christmas with a sweet picture of her and Tristan - whom she's been dating since 2016 - cradling her burgeoning baby bump and accompanied the shot with a lengthy caption.

Asked why she chose to share her baby news on Instagram, Khloe said: ''I just wanted to do something myself and write something that was heartfelt for me. I've wanted to have a baby for so long it's just the perfect timing. God always has a plan and I just wanted to do it on my time and when I felt comfortable to do so.''

Khloe is just three months from giving birth and has admitted she's starting to feel ''uncomfortable now'' because the tiny tot is squashing all of her organs.

She said: ''The baby is on all my organs so I get out of breath just from walking.''

But even though her body is growing a little one, the blonde star is adamant she won't be switching to maternity wear until she can't fit in her normal clothes anymore.

She added: ''I'm gonna try to not wear maternity clothes as long as possible.''

And, although a baby is something Khloe has always wanted, she found the first trimester of her pregnancy the ''worst'' because no one knew she was expecting.

She explained: ''At the beginning, the first trimester is the worst and no one knows you're pregnant yet and you feel the most uncomfortable.

''I think once people know you're pregnant, you get all the excuses. Hopefully I look pregnant, not just fat. It's hard for me to breathe right now.''

Tristan, 26, already has 12-month-old son Prince with his ex-girlfriend Jordan Craig.
