According to Us Weekly, the two began dating in 2001. They welcomed their four children – Ella, 17, Michael, 15, Brendan, 12 and Grace, 11 – before marrying one another. 

"I owe a lot to my wife," Wahlberg gushed during a 2018 interview with The Sun. "She has helped me become the man that I am and created a beautiful life for me and our children."

He continued: "I also knew that she loved me for who I am and that she was someone I could trust. Until I met her, I wasn’t ready to have a family."

The actor was hesitant to start a family because of his own troubled background and fears of not being able to be a good father.

"You need the right woman in your life and that feeling that you’re going to be together for a long time," he explained. "That’s especially important if you’re going to have children. Rhea always wanted to be a mother. She had a job, but her mission in life was to be a mother and to be a wife."
