Nick and Vanessa Lachey have more than one reason to celebrate today.

The longtime lovebirds, who tied the knot three years ago today on Richard Branson's Necker Island estate, are celebrating their anniversary with some exciting news: They are expecting another baby!

The 98 Degrees crooner, 40, took to Twitter to share the monumental announcement and posted a photo of their son Camden, 1, playing on a beach next to a sand drawing of a heart with the words "It's a girl" written inside.

He accompanied the sweet snap with a message about his beautiful wife and family, " Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family."

Prior to welcoming their son in September 2012, Lachey opened up to Yahoo about his wife and how she knew would be a wonderful mother.

"She is great with kids …she is very nurturing. I think she'll be a phenomenal mom."

It sounds like family life suits both Nick and Vanessa. The former Entertainment Tonight host, 33, gushed just as much about her hubby and his parenting skills over Father's Day in June. She accompanied a sweet photo of her main squeeze and their son with the caption, "One of the greatest men I know... there's nothing you can't do, Baby. You are an amazing Friend, Husband and Daddy. We Love you forever and ever."

The duo did not reveal a due date for their baby girl, but it sounds like there will be plenty of love in the family when she arrives.

Interestingly enough, Lachey's ex-wife, Jessica Simpson, revealed that she was expecting her second child in a similar fashion and posted a photo of her daughter Maxwell sitting in the sand with the message, "Big Sis." Coincidence?
