One more makes four for the Lachey family!

Congratulations to Nick Lachey and Vanessa Minnillo, who announced on Twitter today that they’re expecting another baby! The VH1 host and his actress wife are already mom and dad to 22-month-old Camden John.

The former 98 Degrees member tweeted the announcement with a photo of soon-to-be big brother Camden running across the beach, underneath a hand-drawn message revealing baby #2’s gender.

How sweet! It’s hard to believe this celebrity couple has already been married for 3 years. But we have to agree with Nick -- what a perfect way to celebrate an anniversary. Bonus: The next Lachey baby will be a girl, giving Vanessa more even footing with the two handsome guys in her life.

Congratulations again to Nick, Vanessa and Camden!
