John Mayer put on quite a show for the paparazzi when he left My House in Los Angeles at the weekend.

Jennifer Aniston's ex emerged from the night spot covered in lipstick kisses and joked to the paps that he had had “fourteen” girls inside. How could Jen have let this one slip through her fingers?

In a skit he had prepared specially for the occasion, John then busted some Michael Jackson moves while his mates sang Man In The Mirror.

John could do worse than to take Jacko's advice - it's about time he took a long hard look at himself.

We're sure John's act seemed hilarious in the planning stages - unfortunately, it worked less well in real life.
