Charlotte McKinney made it very clear in her Carl's Jr. Super Bowl commercial that she wasn't afraid to show some skin, and now she's showing some on the red carpet.

While attending the Spike TV's Guys Choice Awards on Saturday, McKinney arrived on the red carpet in a racy backless silver dress that showed the top of her butt, according to the Daily Mail.

It's unclear whether the dress was made to go that low or if it was a wardrobe malfunction, but either way, the 21-year-old still looked amazing. The sexy dress showed off her long, tanned legs and her blonde hair was full of perfect waves.

The model recently revealed that she's sick of being compared to swimsuit model Kate Upton or being told she's the "next Kate Upton" just because of her blonde hair and big bust, according to Star Pulse.

She took part in a Q&A on Twitter in the beginning of May and replied to one fan's question about the comparison, saying, "I'm so over it. I believe we're two totally different people and we have different career paths."
