Rapper Earl Hayes shot his wife Stephanie Moseley and then himself in their Los Angeles home yesterday in what cops are calling a murder-suicide. Hayes's friend Floyd Mayweather apparently watched the tragedy unfold on FaceTime. Now, TMZ is reporting that Hayes may have been jealous over his Moseley's alleged affair with Trey Songz.

According to TMZ, Moseley, a VH1 actress and professional dancer, was involved with Songz two years ago:

Sources connected with Hayes tell us ... around 2 years ago he separated from Stephanie because of what he says was her affair with Songz. They got back together but, as one friend put it, "He was crushed and never got over it." We're told he frequently brought up Songz.

Yesterday, TMZ reported that Hayes was angry Mosely cheated with a "famous singer."

Songz tweeted his condolences, but he hasn't commented on the rumors.
