On Friday, Tiger Woods' estranged wife Elin took 11-month-old son Charlie to the My Gym Children's Fitness Center in Windermere, Fla. She was followed by her band of security.
Woods' whereabouts remain unknown.
Tennis pro Roger Federer has spoken to the golfer, 34.
In a new interview with French sports paper L'Equipe, he says Woods will make a comeback "as the wonderful golfer we know."
He says that Woods' infamous car accident and sudden media attention have been rough on the golfer.
Says Federer, "Tiger needs calm."
As rumors surface that Woods is being treated at rehab for sex addition (one blog says he's in Mississippi; another Arizona), the new Us Weekly reports that Woods slummed it on the floor of a deserted house in the days after his Nov. 27 blowout with Elin.
"When she kicked him out, he couldn't exactly go to a hotel, so he ran over to [pro golfer] Mark O'Meara's empty villa and stayed there," says a resident of Woods' luxe Isleworth, Florida, gated community.
Adds the source, who viewed the home after Woods left: "The house was gutted except for an air mattress, some pillows, a TV, snacks and Bud Light in the fridge, and a golf glove on the floor."
