Beyoncé killed it during her Grammys performance, but the “XO” singer looked amazing throughout the night! For most of the evening, Bey wore a lacy gown by former Project Runway contestant Michael Costello with a deep red lip. The “Drunk in Love” singer complemented her gigantic 18-carat Lorraine Schwartz engagement ring with a lot of bling — over $10 million worth, in fact! The sparkles came from a trusted source, as well: Schwartz stepped in to add sparkle to Bey’s form-fitting look.

The superstar wore sparkling diamond chandelier earrings with several cocktail rings on her fingers. She stacked her rings up, wearing three on one finger alone! The jewelry designer was thrilled to work with Beyoncé, as proved by a photo Schwartz posted on Instagram showing herself and Queen Bey backstage. “My muse!” Schwartz wrote, tagging the poss.

During her killer “Drunk In Love” performance at the top of the awards ceremony, Beyoncé sizzled with her husband Jay Z while she got wet and wild in a Nicholas de Carle bodysuit and a custom bra. The sexy look was finished off with Saint Laurent tights, Stuart Weitzman shoes, and Jennifer Fisher earrings. Bey showed off her amazing post-baby body to full effect — and why shouldn’t she? Beyoncé revealed that she lost 65 pounds after giving birth to Blue Ivy.

Miguel wrote some of the lyrics on the smash album Beyoncé and spoke with MTV on the red carpet last night about the process of writing for the living legend. “[She said] ‘Listen, I feel so empowered at this time and place. You don’t have to put me on a pedestal.’ Never mind that it’s Beyoncé,” Miguel explained. “It was so matter-of-fact, and really we were in the studio and she was there, she just had the baby, she was looking beautiful, her skin was glowing and she was ready to create.”

Between her two looks last night, it seemed like Beyoncé was as glowing and sexy as ever!
