Tiger Woods is facing fresh allegations over the extent of his philandering from Joslyn James, a porn star, who claims she fell pregnant by him on two occasions.

The porn star allegedly told a US TV show how she always had unprotected sex with the golf star during their three-year affair.

The actress, who has appeared in adult films such as Big Breasted Nurses and My Sex Teacher, tells Inside Edition that using protection ‘was never talked about’.

James, 32, said she miscarried in her first pregnancy at about the same time Tiger’s wife, Elin Nordegren, gave birth to daughter Sam Alexis in June 2007.

The next pregnancy was aborted close to the birth of Woods’ son, Charlie Axel, in February 2009, James claims.

The golfer was not told about either pregnancy, she said.

James tells the TV programme: ‘I just didn’t want to ruin anything.

‘Actually, the day I was going to tell him, I had a miscarriage,’ she said.’After I lost the baby I didn’t want to talk about it.’

The porn star added that the first pregnancy and miscarriage made her ‘more emotionally attached’ to the golfer.

But she admitted to regrets over how Woods’ wife had suffered.

‘I feel bad for [Elin],’ she said. ‘She didn’t deserve this, and she didn’t deserve being humiliated.’

Asked whether Woods’ wife might have suspected something was going on, James said: ‘Not to my knowledge. But she had two kids at home, and she was stressed out.’

Woods and his wife are believed to be living apart in the same Orlando-area neighbourhood so he can spend time with their children.

The revelations about the alleged pregnancies come after it was revealed that he had cheated on his wife with several women.

Leonardo DiCaprio puts a ring on girlfriend Bar Refaeli’s finger?

With Sunday being Valentine’s Day, it would have been the perfect opportunity to get down on bended knee.

So the question is, has Leonardo DiCaprio proposed to his on-off girlfriend Bar Refaeli?

If the shiny gold ring on her engagement finger is anything to go by, it could the case.

The Israeli model, 24, was spotted with the sparkler as she dined with Leo and his mother at the charity gala dinner at the Berlin International Film Festival today.

Last month the pair were pictured together at a basketball match, setting tongues wagging that they had rekindled their tempestuous relationship.

They split in June 2009, reportedly because 35-year-old Leo was not ready to settle down and move in with her.

On Monday, Leo’s mother Irmelin, 65, joined her son and Bar at the Cinema for Peace Gala 2010 charity dinner. The event is held every year as part of the film festival, also known as the Berlinale.

German newspaper Bild quoted a source saying the actor’s mother had been urging him to make an honest woman of Bar.

Bild reports: ‘His mother previously urged him to marry Gisele Bündchen without success. Now she said to him, “Don’t make the same mistake a second time!”‘

Hair-raising ‘Speidi’

After undergoing 10 cosmetic surgery procedures in one day, The Hills star Heidi Montag is feeling more confident about herself than ever before. Despite her joy over her drastic new look, it appears her husband Spencer Pratt prefers one of the few parts of her that isn’t surgically enhanced.

As the besotted couple celebrated Valentine’s Day in Las Vegas over the weekend, Pratt admitted he loved his wife’s hair more than anything.

While Montag’s hair is obviously dyed platinum blonde, it is still more natural than a lot of her body parts.

The couple co-hosted a special Valentine’s party in the Pure nightclub at Caesar’s Palace on Saturday night.

While the 23-year-old waxed lyrical about the joys of surgery, her husband wasn’t quite so sure.

The 26-year-old told People magazine :'(My favourite part is her hair). It keeps growing so beautifully and naturally.’
