LeoNardo and Rihanna are said to be seeing each other.

Leo and Rihanna meet at the birthday bash of designer Nikki Erwin where sparks flew. The source said that the duo locked lips after getting intimate at the party. The lovebirds were then apparently joined by Paris Hilton,, Hilary Duff, Tom Hardy and a few others. 

Leo also allowed himself to be photographed while Nikki was seen cutting the cake. Leo and Rihanna later headed to an after party where they ran in to rapper 50 Cent. The rapper later loaded a picture on Instagram that has him posing with supermodel Naomi Campbell with Leonardo in the background. 

Interestingly, when Leo's ex girlfriend, Bar Rafeli was asked for a reaction on the blooming Leo-Rihanna affair, Bar quipped, "I think Rihanna is amazing. She must be everyone's type."
