Billionaire Woods, 34, and Nordegren, 29, have been photographed together for the first time since Woods' rampant secret sex life was exposed last November.

They were seen strolling down the driveway of their Florida mansion.

Both are decked out in sports apparel from Nike, one of Woods' few remaining sponsors. They are expressionless as they walk side by side, and it was unclear if she was wearing a ring.

The couple have been spotted kissing outside their home and are believed to be living together there again.

After learning of Woods' affairs with up to 14 women, a furious Nordegren threatened to divorce the star. Now, they appear to be on the mend.

After his spell in rehab, in recent weeks he has been seen at the family mansion in Orlando and at a nearby golf course.

PGA Tour commissioner Tim Finchem said: "I don't have a specific date. He will give us reasonable notice."

CBS TV chief Sean McManus forecast Woods' return would rival US President Barack Obama's inauguration, which attracted 37 million viewers.

"I think the first tournament Tiger plays will be the biggest media event other than the Obama inauguration in the past 10 or 15 years," he said.
