In September 2012, news broke that Shannon and Arrington would share the stage in the Broadway play "Grace," alongside Paul Rudd. At the time, outlets referred to Arrington as Shannon's girlfriend.

Both their IMDb profiles currently state that they're married; however, the couple never publicly announced their marriage. Speaking about "Grace," Arrington revealed that she was engaged when she met Shannon.

"It was a very difficult, painful thing," she said, relating to her character's experience of choosing between what she wanted and what she thought was right. As for working with Shannon, the couple didn't let their relationship get in the way of their professional work.

"The relationship has not made it easier; it hasn't made it harder. It's just separate for us. We really have tried to separate it, and it hasn't been difficult for whatever reason," Arrington observed.

Shannon and Arrington began expanding their family in the late 2000s, welcoming daughters Sylvia and Marion. Since entering parenthood, the girls have become Shannon's top priority. The father of two regarded fatherhood as his most significant responsibility.

"I don't really mind (playing smaller parts). The smaller the part, the quicker I get home to my kids. That's the way I look it," he said. The Hollywood star added that he was nervous about leading roles that required being away from home for a long time.
