Rihanna turned 25 years old on February 20th and she celebrated her big day in Hawaii with family, friends and her boo… Chris Brown.

A party wouldn’t be a party without social media proof… so Rih-Rih shared her big day with fans through a slew of photos she posted online.

Rihanna and her big brother…

I assume this is Rihanna’s online proof that she got “Lei’d” on her birthday…

Happy Birthday Rihanna!
