Livelys latestSNLlook consisted of a silver Tamara Ralph sequin-covered gown, complete with floral embellishments throughout.
For a more monochromatic finish, she accessorized with diamonds and strappy metallic hells.
Reynolds, meanwhile, wore a classic black tuxedo, white dress shirt, and a bowtie.
