A Nervous John Mayer Meets Jen's Father John Aniston and Family

I wonder if they brought up Brad Pitt in their first conversation. Boy to be a fly on the wall in that room. John Aniston was of course on the daytime drama Days of our lives. My grandmother never missed an episode of that. I never got in to the daytime soaps myself. Then again I am always at work when they are on.

Another relationship milestone for Jennifer Aniston and John Mayer — he's met her dad!

The meeting took place on Wednesday at Beverly Hills Hotel's posh Polo Lounge, where John broke bread with 75-year-old Days of our Lives star John Aniston and his second wife, Jen's stepmom Sherry Rooney, plus another older couple. So how did the ever-cool singer do on the dad test? Despite being so nervous that he compared it to "auditioning for Dancing with the Stars," he seemed to be a hit.

"Jen's dad seemed very impressed with John and the two got on real well," an onlooker tells Star.

Dressed in a tank dress and heels, Jen sat next to John — who donned a collared shirt and sweater for the event — in the corner booth. Even though the two sat directly across the table from her dad, "they couldn't keep their hands off each other," an eyewitness tells Star. "Jen was constantly rubbing his hair and John was rubbing her back, then every so often they would steal a kiss. They both looked very happy and very much in love."

Adds another onlooker: "John and Jen held hands under the table. She would put her arm around him and he would reach up and grasp her hands. But John was fidgeting and texting under the table looking a bit nervous."

After starting with a round of cocktails, John and Jen shared a salad, followed by a fish entree. She was even seen feeding him a vegetable off her fork. As for the conversation — led by Jen's step mom, who was much chattier than Jen's dad — it ranged from music to... Tom Hanks.

"John spent a lot of time talking about his music philosophies — why certain decades have better music," says the eyewitness. "He discussed his experiences with Aretha Franklin and made a joke about Tom Hanks."

His nerves showed when Jen hit the powder room. John charmingly asked the table: "How am I doing?" Then cracked, "I am a wreck." Everyone laughed and Jen's stepmom, whom Jen referred to as "mom" throughout dinner, said, "Should we get our score cards out? Like on Dancing With the Stars?" John replied: "Exactly. It feels like Dancing with the Stars."

When Jen returned, her stepmom outed John for being nervous and told Jen that he said it felt like he's on an audition for Dancing with the Stars. Jen laughed and rubbed his thigh.

After the momentous get-together, all three couples left together through the front of the hotel.
