Sean P.Diddy Combs (@iamdiddy), rapper, producer, designer and aficionado of just about everything, shamelessly promoted his vodka brand saying, People!! Go get you a slurpee a 7/11 pina colada mix it with coconut Ciroc.. New drink, its called a P DIDDY... Cuz off the P.. Get it?!

A quick rec for Slurpees by Nick Cannon (@NickCannon), host of hit show America's Got Talent and husband of singer Mariah Carey, sent other twitter users in a mad frenzy of retweets after posting It's free slurpees at 7 11 all day today!

While Shape Magazine points out that Slurpees are not exactly the healthiest drink on the menu, Phoenix Suns point guard Aaron Brooks (@Thirty2zero) will undoubtedly be sipping on one today according to an excited tweet from him.

The annual promotion on July 11th is a big money maker for the company. When they did the promotion last year, 7-Eleven saw a sales increase of 38 percent.
