Charlotte McKinney is celebrating her birthday in Vegas.

On Sunday, Daily Mail posted photos of the model who made her way to the big city and celebrated with a group of lady friends. McKinney sported a sultry black outfit that bared her shoulders and legs as she partied it up with a fluffy pink cake.

One picture shows McKinney tasting the sweet dessert as she looks thrilled to celebrate her 23rd birthday.

It's been quite a year for the model who seems to get sexier in each photo of her that gets released. With more than one million followers on Instagram, McKinney has made quite a name for herself at only 23-years-old.
