Heidi Klum is planning a worm-and-parasite cleanse.

The 52-year-old supermodel has revealed that she and her husband Tom Kaulitz, 35, intend to try out the cleanse as they attempt to rid their bodies of potentially harmful worms and parasites.

Heidi told the Wall Street Journal: “I’m going to deworm and de-parasite for the first time. Everything I’m getting on my Instagram feed at the moment is about worms and parasites. So I’m doing a worm cleanse and parasite cleanse with my husband.

“I heard that you’re supposed to do this once a year, and I’ve never done it. So I feel like I’m really behind. I don’t know what the heck is going to come out.”

She added: “Apparently, we all have parasites and worms. If you are someone who eats raw things every now and then, like, for example, sushi. There are pills (to get rid of them), they have all of these herbs. There’s a lot of clove in there. The parasite hates clove. They also hate the seeds from papaya. We have all this metal inside of us, and it’s also very important that you use this de-metaling stuff.

“I’m starting this now, and you have to do this for months. It’s like a whole thing.”

Meanwhile, Heidi explained that she is constantly on the go.

The former America’s Got Talent judge said: “I feel like I exercise every day because I don’t sit around on the couch. I’m always moving, doing things. I don’t have someone that packs and unpacks for me. I run thousands of errands.

“Today, for example, I have a fitting, then I try on I don’t know how many outfits. It’s clothes on and off, on and off, on and off, on and off. So I feel like I exercise kind of all the time.

“Then we have a pool at home, so I swim a little bit in the pool. And we have a trampoline.”

Meanwhile, Klum is returning to the reality TV series Project Runway after an eight-year absence.

She said: “Project Runway is my first television baby. It’s something that I have helped create, help sell to the network that ended up choosing us at the time. I love the show. I’m proud of the show.

“I feel like we’ve come a long way. We talked about important things on the show that were kind of groundbreaking, I thought, at the time, including body positivity.

“So I feel like, ‘Yes, I’m coming back.’ But you know, in my heart, I was never really gone.”
