On January 23, 2020, the Hellboy actress posted a picture of herself with Carlson on Instagram.
The photo featured her resting her head on her partner's shoulder with a subtle smile while Carlson looked towards the camera.
While the picture spoke volumes of their reconciliation, Blair used the caption to clarify the situation.

"People come into our lives. And sometimes they go. Or you go. And you go on," she began her lengthy write-up, referring to her initial separation with Carlson.
"And you try to put the pieces together in your mind to make sense of it. And sometimes, when you are ready, you may find that person again," the 49-year-old continued.
Heralding herself as the luckiest woman, Blair stated Carlson was the one she wanted to lean on as well as hold up. Then she ended her statement with sweet words that read, "For good. I love you @ronnniecarlson."
After the announcement, Blair was vocal about her relationship with her partner. She regularly posted his pictures on her socials.
And that's not all. The pair even public appearances once in a while.
The lovebirds were spotted taking a stroll while grabbing coffee in Los Angeles in February 2021. They were even seen enjoying a romantic lunch date at Mauro's Cafe in Los Angeles on April 2021.
But the public displays of affection slowly diminished after the pair decided to part ways.
