Not much of a surprise here, but before James Corden took the stage to kick things off at the Grammy Awards on Sunday, the one and only Erika Jayne already managed to slay the show. The Real Housewives of Beverly Hills singer heated up the red carpet in a sizzling, low-cut dress she accessorized with minimal jewelry (if you consider a giant ring and giant studs minimal) and a trendy half-up top knot.

Erika was not only on hand to school everyone on red-carpet style, but also to serve as a special guest on “E!’s Grammy Countdown" and, according to her Instagram, to hit up some after parties.

Erika added a litte something special with her blue shoes.

By the way, Erika's creative director, Mikey Minden, and her RHOBH pal, Lisa Rinna, basically just said what we were all thinking after she strutted down the carpet.
