SPOTTED: Usher Mourns Step Son’s Death In Karaoke Bar… [PHOTOS + VIDEO]

Usher Raymond IV was spotted at Rock and Reillys Pub in West Hollywood a few days ago where he was partying the night away in the wee hours of the morning (August 7, 2012).

The R&B superstar was originally posted up in a private room but when he heard Karaoke going on downstairs, Usher ran downstairs to participate.

Perhaps the loving father wanted to blow off some steam after mourning his stepson Kile Glover, who was buried a little over a week ago. Or maybe it was to shake off the stress of his upcoming custody battle with his ex-wife, Tameka Raymond, who is also mourning her loss.

I heard that Tameka is somewhere spending time with her kids trying to make sense of her Kile’s tragic death, so it was the perfect time for Usher to ?let loose at the bar to sing “where there is love” during his special karaoke rendition of the Jackson 5’s “I’ll Be There” …

According to TMZ?(who obtained the video footage above),?Usher had been hanging out upstairs in a private area with friends throughout the night — but came down around 1am to show the bar how karaoke is REALLY done.

I guess people mourn in different ways. 😯
