John Mayer has taken no time in finding a replacement for ex-girlfriend Jennifer Aniston, it's claimed.

According to US reports, the singer and major player – who split from the Marley & Me star in March – is romancing a 24-year-old beauty called Scheana Marie Jancan.

The model, "aspiring actress" and, er, waitress met John earlier this month at a Beverly Hills party where she was serving.

A source tells Star magazine: “Scheana was shocked and thrilled when John asked her out. She has always thought he was hot, and she said yes right away, writing down her cell phone number on a napkin.

"They flirted the whole time, and he told her she was cute.”

Scheana has apparently been a regular guest at John's Los Angeles pad.

The source adds: “There is always food and beer around. Scheana said she has loads of fun there; it’s like spring break!”
