“There’s a lot of plastic surgery rumours that swirl and I’m the first one to be super honest,” said the 30-year-old reality star. “Everyone was talking about that, saying they must be fake.
“They are real. They are completely 100 per cent real.”
Host Piers Morgan was not convinced, insisting: “You look like you must have had [surgery].”
Kim replied: “That’s what Spanx and masking tape are for.”
However her older sister Kourtney, 31, freely admitted to a helping hand from the surgeon.
“These babies are not real,” she laughed. “I used to make fun of [Kim] when we were little and then I went and got surgery.”
The sisters’ latest reality show, Kourtney & Kim Take New York, debuted in the US this week with a huge three million viewers.
