Last week Lohan Instagrammed this photo of the couple, and a source tells the mag, "He's a great influence on her, and her friends and family love him ... He's older, a successful businessman, and he has been a great friend to her. He's also a Christian and won't drink around her. He's trying to keep her sober and on the straight and narrow. He's really good for her."

Nordgren, 30, played a season of pro football for the Philadelphia Eagles in 2006, and he starred on the 2011 Bravo series Most Eligible Dallas.

Lohan and her new beau met seven years ago through mutual pals in Los Angeles, but it wasn't until recently that the two became romantically involved. "I have been a friend trying to support her for many years now," Nordgren told Page Six. "She's completely sober for months now. She's in a great place, she's thinking clear and working hard and meeting with all the right people."

And Lilo's definitely a step up -- Nordgren was previously linked to The Bachelorette's Vienna Giardi and Audrina Patridge, who really hasn't done much of anything since The Hills.
