The baby's almost here, and this royal beauty's glowing brighter than ever!

Kate Middleton is seven months along in her pregnancy, and naturally, the Duchess of Cambridge is doing all that she can to keep the baby healthy while still keeping up a flawless facade for her many appearances. 

That begins with some big changes to her beauty routine! Middleton, 33, has long indulged in weekly St. Tropez spray tan treatments to maintain her glow. But as she doesn't want to inhale any of the mist while pregnant, she's opted to rely on the DHA-free Bobbi Brown Shimmer Brick in Bronze ($44, Sephora.com) instead, which gives her cheeks fresh-from-the-beach color. 

"Kate is very cautious of products and treatments," a source close to the Duchess told Us Weekly. "Baby's health comes first."

But that doesn't mean she's stopped taking care of herself! To fight fine lines without using potentially harmful retinoids, the mom to Prince George, 19 months, applies Trilogy's Rosehip Oil ($24 at Whole Foods Market), an all-natural oil that keeps wrinkles at bay.

"Kate continues to use rosehip oil in her daily skincare regiment," the sources added to Us. "She loves the effect is has on her skin. [Her mother] Carole [Middleton] is also a fan."
