John Mayer Getting Close With Pussycat Dolls Lead

John Mayer has been spotted "getting really close" to Pussycat Dolls star Nicole Scherzinger.

The musician - who has previously been romantically linked to Jessica Simpson and Cameron Diaz - was seen flirting with stunning Nicole at Los Angeles nightclub Villa last week.

A club insider said: "They were chatting and getting really close - she was into it. They left within minutes of each other."

A representative for John had "no comment" on the new relationship.

Meanwhile, notorious gossip blogger Perez Hilton recently claimed John is bisexual.

Perez - real name Mario Lavandeira - alleged he had kissed John at a New York nightclub last year.

Following the incident, Perez said: "He is definitely bisexual, but he is struggling with his sexuality. He kissed me, and I kissed him back. It was on the mouth with tongue. I thought he was messing with me. Then he kept going and going."
