Vanessa Lachey Baby Bump: Pregnant Star Poses For Maternity Photo (PHOTO)

Time is ticking down! Vanessa and Nick Lachey will welcome their first child in just a couple of months, and from the look of Vanessa's latest photo, she's sporting quite a big baby bump already.

Vanessa posted a beautiful photo of herself in water, silhouetted by the sun, on Twitter Tuesday. The stunning shot, which she reveals was photographed by dad-to-be Nick, was posted after the star teased, "Let's embrace our changing bodies! Show me ur bump & I'll show u mine! Let's get creative!"

We think Vanessa's photo, which we're guessing was taken during the couple's "babymoon" in St. Lucia last month, certainly takes the cake.

Though Nick revealed the big baby news while co-hosting "Live! With Kelly" this spring, the couple has stayed mum on the sex of their baby. However, sources revealed to In Touch Weekly that the couple is thinking blue and expecting a boy later this summer.

This spring, Vanessa replied to a Twitter follower who asked her whether she would prefer to have a boy or a girl.

"I'm excited either way! But I always wanted a boy 1st. Just a healthy baby," she wrote.
