Jennifer Aniston is a busy woman. While she's made every effort to be at boyfriend John Mayer's side during his summer tour, sometimes a girl has to take care of business! But not to fear — Jen, 39, has a backup plan. John simply comes to her!

After playing a show in Phoenix, Ariz., Wednesday night, John snuck back to L.A. to spend a few quality hours with his lady love at her Beverly Hills home.

An eyewitness tells OK! the two spent the night together and the following morning, John, 30, left in his blue vintage Land Rover for a meeting with L.A. officials to discuss potential new laws aimed at the paparazzi.

Then it was back to Jen's for more R&R. The singer finally left around 3 p.m. PT and headed back to his Pacific Palisades home for a workout with celebrity personal trainer Harley Pasternak.

John is definitely devoted to keeping his relationship alive with Jen. He is scheduled to play a concert tonight in Dallas,Tx.
