Looks like Rihanna carried over her #birthdaybehavior well into Thursday!
The Unapologetic songstress covered her bikini bod up with a wetsuit and enlisted world champion Hawaiian surfer/actor Makuakai "Makua" Rothman to help her out!
Check out Rihanna having the time of her life (above)!!
A source spilled:
"She looked totally free and like she was really enjoying her birthday. Chris was protective and made sure to hold her hand as they walked."
Those waves sure look fun! Wonder where Breezy was for this ocean adventure??
Guess she must've had him sit this one out!
