Robert, whose stage name is Spunk Ransom, sat atop a stool center stage and belted out a few heartfelt tunes while strumming along on his acoustic guitar.

Surely every female in the place was imagining that the sloppy haired musician was singing only to them!

Among all the ladies in attendance was Robert's Twilight co-star Nikki Reed, who came out to support her fellow onscreen blood-thirsty vampire.

After the show, Robert stuck around for a bit to have a few drinks with friends and his manager. He was also humble enough to chat with fans and snap a few photos with them.

You gotta love that his new found fame still hasn't gone to his head!

Feel free to drop a comment about what you thought of Robert's performance!
