Tiger Woods and wife Elin Nordegren have spent a week under the same roof according to celebrity gossip site TMZ.com.

The website quoted sources close to the family as saying Tiger has been staying with his family at their Isleworth estate for the past 8 nights.

During that time, TMZ also reports, Nordegren has been seen in the nearby town with a 'rejuvenated demeanor'.

Meanwhile, PGA commissioner Tim Finchem dropped a subtle hint on Sunday that he knows when Tiger Woods will return to competitive golf following his layoff after revelations of adultery.

During an interview with American television network NBC, Finchem was asked whether he could "enlighten us on when exactly" Woods would return.

It wasn't what Finchem said, but what he didn't say that was interesting. Instead of simply saying he didn't know, former debating champion Finchem danced around the question without directly answering it.

"I'm as excited as everybody else to see him back this spring but my sense is we'll know pretty soon," Finchem said.

Some media outlets, including the New York Times, have reported that Woods will not return before the Masters, the year's first major championship set for April 8-11 at Augusta National Golf Club.

Others speculate he will play March 25-28 at the Arnold Palmer Invitational PGA event at Bay Hill or a two-day exhibition known as the Tavistock Cup on March 22-23 between PGA players at rival private clubs near Orlando.
