Rihanna reportedly had a messy night this weekend with sources claiming she threw up while partying at a nightclub.

The 'We Found Love' hitmaker was enjoying a night out at the 1 OAK hotspot in Las Vegas over the weekend with friend and collaborator Ne-Yo, before things turned a little messy for the singer.

According to The Sun, RiRi threw up in a napkin during her long night out, although it isn't known if the alcohol or an illness was the cause.

"She threw up in a napkin. The guy with her handed her a white towel to clean up," an eyewitness told the publication.

After cutting shapes on the dancefloor with 'Let Me Love You' crooner Ne-Yo, RiRi apparently felt well enough to continue with her night and headed to strip club Spearmint Rhino at around 5:30am.

RiRi is known to love a good night out and has been spotted at several clubs in the last few weeks.

Sounds like RiRi may need a night off!
