Even though a security guy is shining a flash light at the camera, you can clearly see John and that's Jen hiding behind him.

John and Jen were spotted last night enjoying a romantic night out at the Ray LaMontagne concert in Hollywood. The couple arrived together and quickly made their way inside. A spy inside the theater told the pair looked very romantic inside the VIP section, where they were seen hugging and kissing throughout the show.

Check out video of the concert below.
