The Tiger Woods effect is in full swing on the golf course, with the revived star attracting great ratings for last weekend's Chevron World Challenge (up over 170 percent vs. last year, even if he did lose). But off the course and at home, things aren't going so great for the superstar, who's been spending less and less time with his kids.

"Tiger spent Thanksgiving with his two kids, Sam and Charlie, and his mother but hasn't seem much of them since the split," an insider tells me. "They spend most of their time with Elin, who is getting on with her life since the ugly separation."
