Heidi Klum’s lips are sealed about this year’s Halloween costume. 

The "America’s Got Talent" judge teased that her holiday ensemble will be "difficult" this year after last year's controversial outfit.

"My Halloween costume is complicated," she revealed to Fox News Digital on the show’s red carpet. "I was almost going to say … I might not be able to come, but I think we're going to work it out now."

Klum, who throws extravagant Halloween bashes every year, is known for her love of epic costumes. She explained why she’s keeping her outfit top secret after she dressed up as a gigantic worm in 2022.

"I think the best thing is always to not give too many hints because then the surprise is bigger," Klum noted.
