Tiger's mistress reveals pregnancy claims

One of Tiger Woods' alleged mistresses has claimed she became pregnant to the golfing star during their three-year affair - twice.

In an interview with American TV show Inside Edition, porn star Joslyn James said both pregnancies occurred as Woods' wife Elin was expecting his children Sam, now 2, and Charlie, 1.

She told Inside Edition she miscarried the first child and ended the second pregnancy through an abortion.

According to the Times Online, James said she and Woods had never discussed or used contraception.

James, 32, also said she had never told Woods about the pregnancies.

"Elin was pregnant with Charlie at that time. I just didn't want to ruin anything," she said.

"Actually, the day I was going to tell him, I had a miscarriage.

"After I lost the baby I didn't want to talk about it."

However, James' stepmother Deborah Siwik has spoken out and expressed doubt about the claims, the New York Daily News reports.

"Joslyn is a compulsive liar and a bad mom," Siwik told Radaronline.com.

"It's possible she got pregnant by Tiger Woods, but she was involved with a lot of other men, too," Siwik said.
