The Diamonds star and rapper Travis were partying with pal Ty Dolla $ign at Project Los Angeles when a group of men began arguing outside the venue, prompting one person to pull out a gun and shoot.

No injuries were reported in the incident and police quickly arrived on the scene, where they briefly detained five people. However, no arrests were made and they were subsequently allowed to walk free.

Rihanna and Travis, who were not involved in the shooting, have been romantically linked since September (15), when they were photographed on a number of nights outs together in New York.

Travis recently dodged questions about their relationship during an interview with Complex magazine, but when asked to describe Rihanna in three words, he chose "creative", "inspiring", and "muse". He did not elaborate on his comments.

The stars will be spending an increasing amount of time together in the coming months after teaming up for Rihanna's Anti World Tour, which will kick off in February (16) to promote her new album, Anti. The Weeknd and Big Sean will also join the singer for select dates.
