Blair's boyfriend was close to her nine-year-old son, Arthur Saint Bleick.
A peek into Blair's Instagram clarified the three spend family time together.
But, most importantly, he also had an apparent good rapport with Jason Bleick, Blair's ex-boyfriend and the father of her son.
On March 17, 2021, the mother-of-one posted family pictures on Instagram, and one photo featured her son, her boyfriend, and her ex-boyfriend.
It's no surprise that Blair had a healthy relationship with Bleick; he was one of the people to support Blair after her diagnosis of multiple sclerosis in 2018.
The duo was together for two years, starting from 2010 to 2012. They welcomed their son in 2011. "We have a flexible custody arrangement and Jason is a huge part of Arthur's life," Blair told People in July 2019.
Besides Bleick, Blair was in a brief relationship with fellow actor David Lyons in mid-2020. In addition, she was married to American musician Ahmet Zappa from 2004 to 2006.
