Nordgren, 30, was a quarterback for the University of Texas before playing one season for the Philadelphia Eagles in 2006. He later went on to star on the 2011 Bravo reality series Most Eligible Dallas.
Insiders say the clean-cut Texan is a good guy for Lohan to have in her life. "He's a great influence on her, and her friends and family love him," a source close to the starlet tells Us.
"He's older, a successful businessman, and he has been a great friend to her," the source adds. "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."
According to Page Six, the two actually met seven years ago through mutual friends in L.A. But their relationship only recently turned romantic.
"We've hung out," Nordgren told the New York Post's Page Six of Lohan, who recently completed a court-ordered stint in rehab. "But I have been a friend trying to support her for many years now."
"She's completely sober for months now," he added. "She's in a great place, she's thinking clear and working hard and meeting with all the right people."
