A few weeks ago, Rumer was seen heading to the Prince concert with her boyfriend Jayson Blair.

Jayson recently shared his audition experience for his show New Normal.

“I kept the clothes on! First of all, it’s totally bizarre to audition a sex scene. So for my audition, I literally was humping a chair. I was actually working a chair and then looking at the casting director. And the way I auditioned it and the way we actually did it was very different,” Jayson said. “But I think it was fun and really unique and gave them the sense that this guy is willing to go here, so if we want to pull him back, we can. He will do whatever it takes for this role in this comedy. He’ll make it work.”
