Rob Gronkowski sleeps with one of his 'fans'.

Let's face it, Rob Gronkowski is the number one party boy in the NFL.

The New England Patriots' star tight end has developed a reputation for enjoying himself mightily when away from the football field, and he seems content to accept his new persona.

'Gronk' took to Twitter to express his secret to a good night's slumber, sleeping with his favorite 'fan'.

Oh Gronk, never change.
