The Daily Grind Video

Before we get distracted by all the thigh glitter in this pic, it’s time to acknowledge Kelly Rowland’s absolute perfection on the red carpet this year. The former Destiny’s Child member ranked on our best dressed of 2013 list, and last night, she reminded us why.

The newly engaged singer was on the scene to celebrate the X-Factor finale, and she brought out all the glitz, glam, and grandiosity for the occasion – but left her engagement ring at home. The Balmain Black Embellished Leather and Suede Gown she wore had more than enough bling to hold her over through the night. She paired the look with Anthony Vaccarello Black Abisko Sandals, and a whole lotta arm candy. #flawless.

Demi Lovato was also in attendance after announcing she will not be returning to the show next season. She wore a gold sequined dress topped with a black blazer, but we’re most obsessed with her blue hair…still.

Mario Lopez was also looking dapper in his trimmed suit.

And Leona Lewis was there…looking impossibly gorgeous and tan and amazing.
