John Mayer Tells Tourist His Relationship Is 'Vague'

JENNIFER ANISTON beware - your man is chatting up other women.

Rocker John Mayer was caught chatting up a pretty U.S. tourist in Amsterdam, Holland last month (Jun08) just two days before his actress girlfriend joined him in the European city.

California girl Chaton Anderson claims Mayer approached her in a cafe and invited her out to dinner.

She tells In Touch magazine, "I think he thought I was from Amsterdam, because he said, 'I am John and I am a singer.' I laughed because I knew who he was."

The pretty 32 year old continued to flirt with Mayer, who appeared to be single.

She adds, "I asked him what his relationship status was. He said, 'It's vague.' I asked him what that meant and he said, `You know, it's very vague.' I just laughed.

"I never mentioned Jennifer and neither did he... I never would have guessed he had a girlfriend at all."

Anderson never got the chance to meet up with Mayer for dinner because she lost her cellphone after exchanging numbers with the guitarist.
