It looks like the Lacheys can start buying blue baby clothes! In Touch can exclusively reveal that Nick and Vanessa are expecting a boy.

Sources tell In Touch that the mom-to-be and her hubby are “so thrilled” to be having a son, as Vanessa wants him to be able to take care of his future siblings.

And while they have been discussing names, they “haven't picked one yet," a friend of the couple tells In Touch.

Vanessa has been quiet about the sex of her baby, but tweeted in March that she “always wanted a boy first.”

The duo looks forward to expanding their family in Nick’s home city of Cincinnati.
