The 31-year-old -- who now goes by her married name, Vanessa Lachey -- took to Twitter on Monday, saying to fans, "Let's embrace our changing bodies! Show me ur bump & I'll show u mine! Let's get creative!"
She followed up on Tuesday with this stunning bikini silhouette photo that her hubby Nick Lachey took while the pair was on their recent babymoon vacation in St. Lucia.
The host of "Wipeout" noted, "Thanks for sharing all your Beautiful baby bumps & embracing your bodies! As promised, here's one @NickSLachey took."
