"Nick and I are incredibly excited to share the news that we are expecting a baby boy," she wrote. "We can't wait to meet him soon!!!"

The baby is reportedly due in September.

Singer/TV personality Nick Lachey, whowill appear next on NBC's "Stars Earn Stripes," married his wife (formerly Vanessa Minnillo) in July 2011. In March, he revealed the couple was expecting during a co-hosting stint on "Live! With Kelly."

"I've had a chance to do a lot of great things in my career and my life but this is the one thing that, more than any other, I look forward to," he said. "The fact that it's actually here, it's overwhelming."

That same month, the mom-to-be admitted on Twitter that while the couple just wanted a "healthy baby," she did have a bit of a gender preference.

"I'm excited either way!" she tweeted. "But I always wanted a boy 1st."
