Heidi Klumis trading in heels for hammers on the season 4 premiere ofCelebrity IOU!
PEOPLE got an exclusive first look at Klum’s heartfelt renovation (above) and chatted with the Scotts about their time with theAmerica’s Got Talentjudge.

In the exclusive first look, Klum puts in her all to transform Lucia’s living and kitchen area into a chic, open-concept space to better accommodate her large family. After using all her strength to install hardwood floors in the home, she hilariously ends up comparing her arm muscles with Jonathan’s using a tape measure.
“I have two and half inches more muscle than Heidi Klum,” theProperty Brothersstar triumphantly announces after comparing their measurements. “I’m not doing too well then,” Klum jokes.

Drew reflected on his time spent with Klum, telling PEOPLE how the model gave him some pointers to kickstart his next career change.
“It’s important because that’s my next career,” he jokes. “Runway modeling. Victoria’s Secret, that’s not my name. Victor’s Secret, that’s my kind of line that I’ll model.”

While the brothers had their fair share of fun during the renovation process with Klum, they shared that the best part of making the show is watching the homeowner’s react to their completely transformed house.
“Nothing is sweeter than the moment when you hand the keys back over and you say, it’s yours, and you’ve changed somebody’s life. It feels really wonderful,” Jonathan tells PEOPLE.
Adds Drew, “To be a part of that, and for these celebrities to bring us into the fold and trust us to be able to help them give back to someone they love, that really means a lot.”
