A shooting occurred outside of a popular Hollywood nightclub where Rihanna was hanging out with friends on Wednesday.

The 27-year-old singer was seen leaving Project Los Angeles after a fight erupted among 'a few guys' outside the entrance and one of them pulled out a gun and fired a single shot, TMZ reported.

The shot was heard among clubgoers inside the establishment and caused a commotion, according to the news site.

Rihanna, who was joined by fellow recording artists Travis Scott and Ty Dolla $ign, appeared calm as she walked out of the club, according to video footage posted on TMZ.

She was wearing a black hooded jacket over a grey top along with bright red lipstick.

Her hair was loose and cascaded around her shoulders while she strolled around to the door of a waiting black SUV parked at the curb.

It's not known what caused the argument among the men in front of the night spot.

Following the shot, police arrived immediately to the scene and handcuffed five individuals although TMZ reported that no one was placed under arrest.

Rihanna's pal Ty Dolla $ign had performed earlier in the day at TDE's second annual Nickerson Gardens holiday concert, according to hotnewhiphop.com.
