Twilight star, Robert Pattinson uses his interest in music to raise money for charity.

The 23-year-old was asked to sign a Fender Telecaster guitar after he strolled into Norman's Rare Guitars in Tarzana, California and started strumming on it.

The shops owner, Norman (surprisingly) Harris, asked the lvoely Rob to sign the guitar and have his photo taken with it.

The guitar is now up on eBay with a reserve price of $3,000 and all proceeds will go to the LA based homeless charity, The Midnight Mission.

Of RPatz, Normy said: "He's really a nice guy - very shy, very quiet."

Aww! Will you be bidding to win the guitar? Hell, we can't even play one but might be tempted to bid anyway!
