We basically have no idea who Charlotte McKinney is -- other than we think she was some sexxxy chick in a Burger King ad, but her cleavage definitely caught our eye last night when she was leaving Hollywood newest hotspot, Catch.

The 23-year-old put her cleavage on display when she went braless in a sexy black top during a night out with a girlfriend. The blonde also paired the revealing top with some skintight, strategically ripped pants. Meow!

Unfortunately Charlotte seemed a little lost upon leaving and couldn't seem to locate her vehicle -- but we were happy to help the hottie find her car. We're so chivalrous!
