When Jett and Jax get older it will be hard for them to explain how they have the same parents and are the same age, but aren't twins.

In fact, the two infants, the sons of Caprice Bourret, a former model who now designs lingerie, and her partner, Ty Comfort, were born almost a month apart. Bourret has now revealed to The Daily Mail that one of her sons arrived via surrogate, while the other she gave birth to naturally, though she won't say which boy is which.

The 41-year-old told the publication that she felt her options for natural birth at her age were limited, after she miscarried once and went through three failed rounds of IVF.

After a surrogate got pregnant on behalf of Caprice, she was surprised to find out one month later that she too was pregnant, a fact she picked up on while doing the celebrity diving show, Splash!

While filming she would often get out of the pool exhausted and covered with bruises, and finally, she decided to see why.

"When I found out I bought a dozen pregnancy kits, peeing on sticks for ever. Then I Screamed and screamed. Ty thought something terrible had happened," she said.

Her first baby was born in August, and she gave birth to her second baby in September. The boys have changed her life around.

"My babies are my entire world now," she said. "I have re-invented myself. I used to be a bit of a wild child, now I am a yummy mummy. My old life is gone."
