Pregnant reality TV star Kim Kardashian West isn’t just posting nude photos of her baby bump on Instagram, she’s also proving its authenticity while working out. During an outdoor workout session with her family, she decided to lift up her shirt to show off her bare pregnant belly.

Kim and most of the members of the Kardashian-Jenner clan are in St. Barts Island in the Caribbean for their annual family vacation. It was previously reported that she was seen attending a beach workout session with her sisters Kourtney and Khloe Kardashian on Tuesday.

New photos have now emerged from the little outdoor fitness session and in one of them, Kim could be seen with her bare pregnant belly in full view. In the photo shared by E Online, Kim is standing on the beach wearing her all-black workout gear. For some reason, she has her tank top pulled up all the way above her bra. The shirt is rolled up to reveal her entire bare belly.

In other photos shared by People, Kim’s sisters Khloe and Kourtney could be seen running through the water with a personal trainer. The “Keeping Up with the Kardashians” cameras ae also following close behind.

This isn’t the first time that Kim has shown off her bare belly during this pregnancy. Amid various reports accusing her of faking her condition, she took to Instagram last week to prove that she really is pregnant.

She posted a nude photo of herself, which clearly shows her growing bump. She is now about six months along and is expecting a son with her husband, Kanye West. She wrote, “First they said I'm too skinny so I have to be faking it...Now they say I'm too big so I have to be faking it...SMH!”

Kim and her family arrived at St. Barts on Monday. Apart from the Kardashian girls, their younger sisters Kendall and Kylie Jenner are also on the trip. Family matriarch, Kris Jenner, has also been spotted along with her children and grandchildren. Scenes from the vacation are expected to be seen when Season 10 of “Keeping Up With the Kardashians” returns in November on E.
