Chris Brown and ex-girlfriend Rihanna have taken to Instagram to pay tribute to dancer and VH1 Hit The Floor star Stephanie Moseley after she was shot dead by her husband yesterday (December 8).

According to TMZ, Moseley - who was previously a backing dancer for Breezy - was killed by her rapper husband Earl Hayes at a high-end LA apartment, with him later committing suicide after shooting her dead.

[related]Hayes - who was previously signed to Floyd Mayweather Jr's record label - is thought to have FaceTimed the boxer at the time of the incident.

The website claims that Mayweather was a witness to the murder-suicide, and pleaded with Earl not to kill his wife - with the dispute allegedly caused by her alleged infidelity with a famous singer.

Residents nearby reportedly heard screams and gunshots coming from inside the apartment, before the SWAT team arrived and found them dead.

Shortly after the news broke, Brown took to Instagram to pay tribute to Stephanie, writing: "RIP baby girl. Danced with me on tour and was always the coolest person. My prayers go out to you and HAZE family.”

RiRi also posted a snap of Moseley, along with the comment: "r.i.p. Stephanie."

Mayweather is yet to comment on the incident.

Breezy's now ex-girlfriend Karrueche Tranalso posted a snap of herself and Stephanie on Twitter, writing next to the pic: "My heart is so damn heavy. This has been one hell of a week. RIP Stephanie.Such a beautiful soul!!!"

She added: "I'm really just so sad with everything going on right now in the entire world. I just want to get in my bed and cry."
