Although you would think things are pretty serious if he's playing party planner for her and packing on the PDA, TMZ reports that the birthday girl is much more into it than The Wolf of Wall Street player. They say the "Diamonds" singer was "clingy" and "following him everywhere", even though it was her big night.
This is surprising to hear since Ri is such an independent, bad ass babe...we hope she's not going to let Leo have the upper hand in this relationship. A party guest posted this Instagram video of Rihanna looking beautiful as she blew out the candles on her cake.
Happy birthday, Rihanna...here's hoping Leo treats you right!
