If there's anybody who knows how to light up a red carpet simply by being there, it's Rosie Huntington-Whitely. The whole "with child" thing doesn't hurt, either—neither does being Rosie Huntington-Whitely—but it also helps to have somebody on your side whose artist's specialty is "glow." If there was a glow whisperer in Hollywood, or anywhere, it's makeup artist Kate Lee. Her assistant once told her that she wields highlighter "like a surgeon." It hardly makes sense, and yet, it's all the endorsement we needed to hop on the phone with her last night to talk face. Without further ado: ITG's Guide To A Glowing Like A Pregnant Former Victoria's Secret Angel.

Step 1: Choose your skincare wisely.

Like all great makeup looks, Rosie's began with a solid skincare base—but for something like this, not any moisturizer will do. Opt instead for something that imparts radiance, like Chanel's Hydra Beauty Flash Balm. Honestly, anything with "radiant", "flash", "glow", or "Rosie Huntington-Whitely" in the product title will work just fine.

Step 2: Highlighter first, then foundation.

Right? We know. But it's the technique Kate swears by. "I like to incorporate highligther first, as a part of foundation," she told us. "I like to put the luminosity in the skin first and then spot treat. Bare cheekbones and luminizer is a good look. I used Rosie's Marks and Spencer's Starstruck Highlighter Stick, the shade of which is a nice nude, on the cheekbones and the top of her lips. Then I used Chanel Vitalumière Aqua under her cheekbones, on the forehead, and chin, applying with a damp Beautyblender. You're creating light with highlighter and diffusing it with the foundation." The effect is a glow that isn't wet-face, but innate.

Step 3: A little more highlighter.

Including, especially, along the jawline. This is somewhat unique to Kate's technique—"it's just something I do. It really makes the skin look tight and taut. Red carpet is an art, and you've got to work with every angle."

Step 4: Resist the urge to highlight any more.

Let the glow be the makeup look. Everything else should supplement. In Rosie's case, this means an understated cat eye (drawn with Chanel's Longwear Cream Eyeliner), a wash of contour (Kevyn Aucoin Sculpting Powder in Light), and a little flush on the apples of the cheek (Chanel Joues Contraste Rose Bronze). OK, that last blush has a tiiiny bit of sparkle to it. "But that's the best kind of blush," says Kate, "because it's a little bit dimensional. It catches the light." That's what it's all about.
