In an oops moment, Heidi made a slight mistake, congratulating Kristin on the impending arrival of a baby boy, when Kristin actually doesn't know the sex of the child.

Heidi tweeted at Kristin: "CONGRATULATIONS on having another boy! You must be thrilled!!!!!! So excited for you and Jay! Sending my love to your family!"

Kristin, who is already mum to one-year-old son Camden, replied: "Lol...@heidimontag jumped the gun...we don't know the sex ;)."

Heidi responded: "Ha I guess not another boy, another a baby! Oops! Super exciting either way!"
