Rihanna is partying way too hard these days. The singer who partied her way throughout the summer on a yacht was seen getting sloppy with it at 1 OAK in Las Vegas with Ne-Yo. Sources who were at the nightclub reveal RiRi was so out of it that she began to VOMIT while she danced!
The source reveals:
â€œShe threw up in a napkin. The guy with her handed her a white towel to clean up.â€
