Jennifer, 42, was filming an interview with James Lipton for the Bravo TV series Inside the Actor's Studio, while her new beau sat in the studio to watch. According to an eye witness, the pair were making "eye contact" throughout the three-hour filming, with Jennifer seeking reassurance from her lover in between takes.

"[He] was sitting in the front row, and she made eye contact with him," a source told People magazine. "Whenever there would be a lull, she would just look at him and give him a wink and go back to what she was doing."

Jennifer, who hasn't been open about any of her relationships since her 2008 split from serial-dater John Mayer, was also a hit with the show's audience. The stunning star drew hoards of laughter when she quipped "Well, you know it's something I have a lot of experience with," when asked about her 2006 movie The Break Up.

Jennifer's down-to-earth nature struck a chord with the audience members. The American actress, who had a high-profile divorce from Brad Pitt in 2005, impressed the audience with her charming nature.

"She was just so relaxed and so open," the source added. "So loveable from beginning to end. Such a sweetheart."

James has revealed he was also captivated by Jennifer's sincerity. The TV personality says the blonde beauty is just as funny off camera.

"She's as quick and witty and charming as she is on screen," he said after conducting the interview.

Jennifer and Justin hit it off while shooting comedy Wanderlust last year and are believed to have been dating for a few months. The relationship is believed to be making pace with Justin reportedly moving into Jennifer's Los Angeles home.

The interview will air next month on Bravo. (C) Cover Media
