Brooklyn Decker hoping firstborn will tie birthday record

Model-turned-actress Brooklyn Decker is hoping the birth of her first child will put her family in the record books.

The 27 year old, who is married to tennis hero Andy Roddick, shares the same birthday as her mother and grandmother - and she's secretly hoping her firstborn continues the family birth date tradition.

Decker explains, "(My birthday is) April 12th and my mom has told me the exact date of penetration - it's July 28th... I have not asked (my grandmother).

"Apparently we'll be tied, I think, for the Guinness World Record if I have a child on my birthday."

And what makes the current family birthday triple so amazing is her mom and dad weren't even trying to have a baby when Decker was conceived.

She tells chat show host Chelsea Handler, "I was a complete accident!"
