The Willis family is ready for its close-up!

In the season finale of TLC’s hit reality series, all 14 members of the musically-inclined Nashville clan welcome PEOPLE Magazine into their home for a photo shoot.

“We’ve worked with a lot of photographers before, but this guy was really cool, really creative. He had a lot of good ideas,” says 13-year-old Jasmine Willis about photographer Peter Yang. “I think the pictures are going to turn out great.”

But with two parents, 12 siblings and a few pets in the mix, getting that perfect picture wasn’t easy. “If our dogs can just be quiet and stay out of the shot, we’ll be cool,” says Jessica, 23.

Since their appearance last year on America’s Got Talent, the Christian family has released an Irish-pop album (their third) Heaven and become weekly fixtures on TLC.

But mom Brenda, 46, says their fame still comes as surprise: “We were just following a path, and we weren’t sure where it was going,” she says. “It’s a roller coaster. Wherever the track goes – up and down – we just need to put our hands up.”
