Chris Brown's girlfriend loves to post photo, documenting her life on the internet. She continued the tradition with uploading images with her singer friend on Saturday.

"She x She...always great to see my Lil Kitty cat!!!" said Rihanna.

Perry didn't just hang out with the Bajan beauty this weekend. The long-haired performer also arrived, all bundled up in a large winter coat and scarf, at LAX Airport on Saturday in Los Angeles.

The "ET" singer just also dished about her role in "Smurfs 2."

"I blocked out a couple of days to prepare for it, because I get into a zone where I really have to turn it on," said Perry to Express about playing in the animated film. "Smurfette isn't my normal voice - it's like my voice and a bag of rocks, with a pinch of sugar."

Rihanna is busy with her new Bravo reality TV show, "Styled to Rock," and promoting her new single, "What Now." 

RiRi has also been the subject of romance rumors, for many fans suspect she is dating rapper, Drake.
