Charlotte McKinney Makes Drum Playing Look Extra Sexy

On Tuesday, the supermodel added a black and white snapshot on Instagram where she mentioned that she worked security at a Grammy party. And based on how she looked that night, everyone should've known to not mess around with her.

McKinney sported a tight black dress that showed major cleavage and lots of leg. With a low cut in the center of the dress, a strong image of her chest was visible as she made it clear that she was the boss that night.

The model stood next to a man in a suit who looked just as serious about the security status as much as McKinney was.

The 22-year-old just spent Valentine's weekend in Aspen where the weather looked freezing based on a couple other photos she added to social media. As she sent her love from the snowy grounds, she managed to pose like a rock star even when she's on vacation.
