Joe Jonas 'Really Focased' on Taylor Swift

Joe Jonas attended Taylor Swift's concert at the Cruzan Amphitheatre in West Palm Beach, Florida, Sunday night, reports E! News.

Concert promoter Mishelle Rivera spilled, 'He arrived about five minutes before the show started and stood next to the soundboard. He was wearing a Yankees baseball hat and trying no to be noticed. He was really into the show. You could tell he was really focused on her.'

Rivera said that Joe rarely took his eyes off Taylor during the entire hour long set and that he immediately went backstage to see her following the show..

Joe took time off from his busy touring schedule to make the show. He played a concert with his brothers in Holmdel, New Jersey Saturday night and tonight will play at the Verizon Wireless Amphitheater in Virginia Beach.

Taylor, who earlier in the week shot scenes with JB in NYC for their 3-D movie, mentioned Joe in her most recent blog: 'I’ve had an awesome week, I’ve been in NYC shooting for the Jonas Brothers 3D movie.

It’s been so much fun! We stayed right across from Central Park and I could see the whole city every time I looked out my window.'

Ryan Seacrest recently asked Joe if he was dating Taylor on his radio show. Joe said, 'I think anyone would like to go on a date with her.'
