“My 14yr old bro is askin me to go to Vegas with 6 friends next yr for his 15th bday, LOL! What ever happened to ‘where do babies come from’?” Rihanna tweeted.

“Oh there’s an alternative here, The Bahamas! This is a lil more like it…dolphins, beach, sun+fun,” she added.

Ri herself will be heading to Sin City to host a New Year’s Eve bash at Pure!
