According to photos obtained by RadarOnline.com, Elin, 39, was seen at her 10-year-old son Charlie's flag football game, sporting a round tummy. She shares both Charlie and daughter Sam, 11, with Tiger, 43.
While the father's identity is unknown, the Swedish model dated billionaire Chris Cline after her divorce with Tiger in August 2010. After one year of dating she and Chris, 60, split in 2014 but got back together in 2016.
As OK! readers know, Elin and Tiger called it quits after news broke that the golfer cheated on his wife with as many as 120 women during their five-year marriage. The blonde reportedly received $100 million as part of their divorce settlement.
At the game, the blonde proudly showed off her baby bump in a pair of black leggings and a black t-shirt while she sat in a lounge chair and watched her son play on the field.
Elin's appearance comes as a surprise considering she is almost never seen in public these days.
"Elin has been staying out of sight,” a source told Radar. “It’s been Tiger and his girlfriend Erica Herman at soccer games and flag football recently.”
The same insider added that no one had any idea that she was expecting! "When Elin showed up, no one knew she was pregnant," the source said. "She has to be a few months. If not a few months, then further.”
