Bad Rihanna....

Word is Rihanna was kicked out of her cousin's wedding back in October for wearing a sleazy dress and busting out the diva.

According to The Enquirer, "No one expected her to show up at the wedding dressed like she was on stage. She was the center of attention instead of the bride, and the bride and groom got upset." Betch.

Rihanna went to her cousin Nigel Alstrom's wedding in Barbados on October 27. "She put on a show- blowing kisses to fans as she entered the church."

A family source said, "She should have been more low-key, dressed appropriately and not have had such a star attitude. She had words with her aunt and mother, and was asked to leave." Before she left she allegedly said, "What am I supposed to do, come dressed in a paper bag?" Yes. Next time just think Diane Keaton.
