Kevin posted a photo of his bride and himself along with the teaser Pink or Blue? Fans with the smartphone app will be the first to find out this Thursday at 6 p.m.

Of course, Kevin isn't the only person excited to share the baby news, Danielle is tweeting her excitement as well. "Iam freaking out Iam so excited to share this news with all of you !!! So get that Jonas brothers app !!" she wrote on her Twitter account.

The Jonas Brothers app is a news application that allows fans to find out all the latest information on the "First Time" band. The application also allows fans to watch streamed interviews with the Jonas Brothers, find all their Twitter posts in one place and interact with other fans.

Sometimes, like this Thursday, the app even includes exclusive content.

So, what do fans think? Will it be a little Jonas brother or sister?
