Heidi Montag: Kristin Cavallari Is Having A Boy! Oops, Nevermind

Heidi Montag may have let the cat out of the bag. The former Hills star accidentally revealed that Kristin Cavallari was having a baby boy this week on Twitter.

The Social News Daily reports that Montag was sending her friend a congratulatory message on Twitter, when she accidentally shared a little too much information.

Montag writes: “CONGRATULATIONS on having another boy! You must be thrilled!!!!!! So excited for you and Jay! Sending my love to your family!”

Cavallari, who already has a little boy with Jay Cutler, announced earlier this week that she was pregnant. Cavallari hasn’t said if she is having a boy or a girl and she may not even know yet.

The former Hills star responded to Montag on Twitter, writing: “Lol…@heidimontag jumped the gun…we don’t know the sex.”

Montag was quick to apologize saying that she made a mistake.

Heidi writes: “Ha I guess not another boy, another a baby! Oops! Super exciting either way! Xo”

Do you think Heidi Montag accidentally revealed the sex of Kristin Cavallari’s baby? Or did the former Hills star simply make a little mistake?

Cavallari announced that she was pregnant this week, but it’s unclear how far along she is. Judging by a few recent photos of the star, she is still pretty early into her pregnancy. Parents.com reports that most parents find out the baby’s gender at about 18-20 weeks, so it’s doubtful that Cavallari even knows if she’s having a boy or a girl.
