Jaws dropped when Halsey hit the red carpet with her plunging silk blue trench coat and matching high-waisted trousers. Since the "Closer" singer doesn't go a day without wearing falsies, it should come as no surprise that she paired her sleek and sporty look with sky-high lashes and a dewy complexion, which was elegantly embellished with a statement necklace and hoop earrings.

Just when we thought we'd finally recovered from her amazing Super Bowl performance, Lady Gaga strutted onto the red carpet ready to kick ass and take names. While Gaga has traditionally always rocked out-of-the-box looks (remember the meat dress), mama monster was clearly feeling fierce this year with her peach ponytail and cutout body suit.

To get her badass ponytail, celebrity stylist Frederic Aspiras prepped Gaga's hair with the GHD Total Volume Foam, $24, massaging it from root to tip, then combing through. After blow drying Gaga's hair with the GHD Air Hairdryer, $199, Aspiras sectioned her hair and sprayed each piece with the GHD Curl Hold Spray, $24, before curling Gaga's hair with the GHD Classic Curve Curl Iron, $199, and let the curls cool for ten minutes. Once cool, he brushed out Gaga's curls and applied a drop of GHD Smooth & Finish Serum and tied it up into a ponytail. Aspiras then went in and added smaller curls for volume and texture in the pony, using the GHD Gold Professional 1", $199.

First-time Grammy-nominee Demi Lovato looked radiant in her crocheted gown and gold lined eyes, which showed off her bronzed complexion. Her long dark hair was the perfect contrast against Lovato's sun-kissed skin, and highlighted her bronzed smoky eyes.

Lovato teamed up with celebrity makeup artist Jill Powell who used the Giorgio Armani Eyes to Kill Intense Eyeshadow, $35, in #5 on her lids and Giorgio Armani Eyes to Kill Solo Eyeshadow in #5 and #7 to add depth. To complete the look, she swiped on the Giorgio Armani Eyes to Kill Quad Eyeshadow Palette, $60, in #10.
