Jennifer Aniston "fits right in" with the crew and musicians on John Mayer's tour, a friend of the rocker tells People magazine.

"John has such an amazing crew of musicians and friends with him. Everyone gets along and is drama-free. Everyone really loves her."

The friend also said that Mayer and Aniston "are very happy together, it's working really well and they're only getting closer. His friends think she's great for him."

Aniston, 39, continues to draw scrutiny when attending the 30-year-old Mayer's concerts. At a recent concert in Chula Vista, Calif., anonymous text messages were displayed on twin screens between acts, and many discussed Aniston, including one that said, "We want Jennifer Aniston to come out now!!!"

At the concert, Mayer commented on the media coverage of his relationship, telling fans that "it's kind of a new thing for me to have my stage banter scrutinized. They have been printing everything I say."
