Country star Keith Urban showed his generosity at a concert in New York on Wednesday (13Feb08) night, when he stunned a fan by giving her his guitar. The singer, who was co-headlining a show with Carrie Underwood in Madison Square Garden, jumped into the crowd during the song You Look Good In My Shirt and picked out lucky devotee Marissa as the winner of his prized instrument. She tells celebrity blogger Perez Hilton, "Keith came into the crowd and into my row... And then as I was taking pictures he whipped off his guitar, signed it and handed it to me! I almost died." And Urban took the opportunity to send his pregnant wife Nicole Kidman - who is currently resting in her native Australia - St. Valentine's Day wishes, telling the crowd, "It's Valentine's Day here tomorrow but today it's already Valentine's Day in Australia."
