Mark Wahlberg's Catholic faith is the 'most important' part of his life and often goes to church twice on Sundays.

The 'Lone Survivor' star, who has four children, Ella, 10, Michael, seven, Brendan, five, and Grace, three, with his wife Rhea Durham, is extremely religious and his Catholic faith is ''the most important'' part of his life.

The 42-year-old actor told Parade magazine: ''It's the most important part of my life. I don't try to push it on anybody and I don't try to hide it.

''If the kids are good, I'll have doughnuts for them at 6:30 in the morning, and I'll say, 'You guys gotta let Mommy sleep in!' I'll go to church at 7:30 and everybody will be eating breakfast when I come home.

''Then we'll go to church again at 10:30, if things aren't too hectic. Or if one of the kids has a game we'll watch them play. It's a nice family day.''

The 'Pain & Gain' star likes to spend as much time as possible with his family when he isn't working.

Asked who is in his entourage, he said: ''My wife, the kids, and a wonderful nanny. When I'm filming, all the guys are with me; but if I'm not at work, I'm with my family.''

Despite his success, the former rapper and underwear model, who lives in Boston, is still very ambitious.

He said: ''I don't think it was customary for people from a music background to be accepted in film in a serious way. Considering what I had to overcome, I've had plenty to motivate me. Even more so today-I'm passionate about what I do. I'm a little older, but I'm not getting lazy.''
