Tiger Woods' ex-wife Elin Nordegren is pregnant with her third child, nine years after splitting from the golf pro. 

The 39-year-old Swedish former model, who shares a daughter Sam, 11, and son Charlie, 10, with her 43-year-old former husband, was seen showing off her growing baby bump at her son's flag football game last Friday, according to Radar Online. It was revealed that the pregnancy has been kept very much under wraps —  and the identity of the father has not been made public. 

'When Elin showed up, no one knew she was pregnant,' a source told the outlet. 'She has to be a few months. If not a few months, then further.'

Quiet life: The 39-year-old former Swedish model has kept a low profile since she and Tiger (pictured in 2006) divorced in 2010 following his infamous cheating scandal 

Elin didn't appear to be wearing a wedding band or engagement ring at her son's game, and it is unclear who the father of the child is.

The former model was last linked to billionaire coal magnate Chris Cline, whom she began dating after they met as neighbors in 2011. The two were rumored to have split in 2014, but they were spotted kissing on the ski slopes in 2016.   

Happy: Tiger, 43, was smiling brightly ahead of the U.S. Open in Pebble Beach, California, on Wednesday 

Both Elin and Chris keep a low public profile and have not spoken out about their relationship. She has also not addressed the news of her pregnancy publicly, other than stepping out with her bump on show.

The mother-of-two was seen holding her stomach with her hand and chatting on her cellphone during the rare public sighting. 

If the news has reached Tiger, it doesn't seem to be bothering him. He was seen smiling brightly during a practice round ahead of the 2019 U.S. Open in Pebble Beach, California, on Wednesday. 

Elin has kept out of the public eye since she and Tiger divorced in 2010 following his infamous cheating scandal.

The source noted that Tiger and his girlfriend Erica Herman have been the ones attending his children's soccer and flag football games in recent months.

The person added that when the athlete is out of town for golf, Sam and Charlie have been with their nanny.  

Elin and Tiger wed in 2004 and were just shy of their sixth wedding anniversary in 2009 when police were called to their home in Orlando, Florida. The golf star had smashed his car into a tree during what appeared to be a lover's spat.

Elin broke her silence about her divorce in 2014, telling People that she and Tiger were co-parenting with ease.  

'I have moved on and I am in a good place,' said Elin, who her earned her psychology degree from Rollins College that year. 

'My relationship with Tiger is centered around our children and we are doing really good — we really are — and I am so happy that is the case. He is a great father.' 

A year later, Tiger told Time that he and Elin have a great relationship after their divorce. 

'She’s one of my best friends,' he said. 'We’re able to pick up the phone, and we talk to each other all the time. We both know that the most important things in our lives are our kids.'

In 2016, he elaborated on his comment during an appearance The Late Show with Stephen Colbert.   

'It becomes two simple things, OK? We have Sam and we have Charlie,' he said at the time. 'And we love them so much that we are going to whatever it takes to make that work. That’s how it happened,” he said to audience applause.

'She’s been one of my best friends and I’ve talked to her about so many different things and she does the same thing with me back and forth,' he explained. 

'We communicate so much better now, it’s incredible. I wish we would have done that earlier on, but it’s been incredible to have a best friend like that.'
