The 37-year-old supermodel mom and her musical hubby, 47 – who recently renewed their wedding vows for the fifth time – have a reality show with Lifetime in the works called Love’s Divine, a rep for Klum confirms to PEOPLE.
"Heidi and Seal have been inspiring people with their idea of renewing their vows each year," a friend of Klum’s tells PEOPLE. "After getting positive feedback from family and friends, they decided they wanted to help others share the same kinds of special moments. For example, they want to help people who didn’t have their dream wedding the first time around to get a second chance."
Although filming has not yet begun, Klum believes her blissful experience as a wife and mom is just the right formula to make the show a success.
"[Seal and I] make special moments into something big and noticeable for everyone in our family," Klum tells PEOPLE. "For birthdays, we handcraft special cards and gifts. We hang welcome signs when Dad comes home from long travels or when the tooth fairy comes at night. With a family of six, there is always something to make, create and do together."
But Klum is staying mum on the specifics of the show. "That’s all I can say for now," she says. "It’s way too early to even talk about it."
Klum and Seal have already served as inspiration in the romance department: Fergie and Josh Duhamel, who also recently renewed their wedding vows, said they took a cue from the happy couple. "We want to do it every year," Duhamel has said. "We got that idea from Heidi Klum and Seal … I thought it was a great idea. "
