Rihanna's rumored boyfriend surprised her with a 22nd birthday party at the weekend.
The "Rude Boy" singer was "shocked" by the bash put together by baseball player Matt Kemp in Phoenix, Arizona - where Kemp is currently training - as she was only expecting a small gathering of friends.
A source said: "It was so sweet and she was really surprised. She looked just beautiful."
Matt organized Caribbean food to be served to Barbados-born Rihanna and also reportedly bought her a custom-made diamond necklace.
The party was extra-special for Rihanna as she canceled her 21st birthday celebrations last year in the aftermath of her assault at the hands of then-boyfriend Chris Brown early in February 2009.
The source added to website "E! Online": "Matt really wanted to do something nice for Rihanna this year since she didn't have much of a 21st birthday last year."
"It was just her closest friends, good Jamaican food, a photo booth, dancing and a nice cake."
Matt, 25, has been linked to Rihanna since they were seen holidaying together in Mexico in January, but he has played down romance rumors.
He said: "Rihanna is just a friend, a good friend of mine. We went down to Mexico and had fun together."
