Best place to meet him:
"At a function or party," says Roddick, who has been dating model Lauren Bedford since his split from actress-singer Mandy Moore
in March. "I don't do blind dates. That's begging for punishment. I'm not comfortable in a bar; the cheese factor is high."

You probably haven't heard of him:
"But in Europe they all know fencing, so it's like being a tennis star or a golfer in America. People will come up to me with posters of me to sign. It's bizarre."
He wears another hat:
When he's not training for the Olympics, he's a financial analyst for Verizon in Newark, N.J.
He needs his own space:
"If I'm sleeping over, I need my own corner with my stuff. I don't want my clothes or bag to be touched. I'm obsessed with 'my' area and 'your' area."
