Heidi Klum celebrated her son Henry's 21st birthday by giving him a red Ferrari F430.
The surprise was captured on video on Saturday, showing Henry walking outside with his stepfather, Tom Kaulitz, before seeing the sports car.
Henry appeared stunned as he took in the vehicle, while Klum filmed his reaction and reminded him he had been waiting for this moment for years.
The Mario Kart Bet Behind the Gift
The car was promised to Henry when he was a teenager, according to throwback footage shared by Klum.
Henry won a bet with Tom during a game of Mario Kart seven years ago, earning a promise that Tom would buy him a Ferrari when he turned 21.
The Tokio Hotel guitarist said he bought the Ferrari at an auto show last year and kept it hidden in the garage until Henry's milestone birthday.
Klum marveled that the promise had been made roughly seven years earlier, with Tom ultimately making good on his word.
Henry is one of Klum's four children, whom she shares with ex-husband Seal. Tom married Klum in 2019 and has become a major part of the family.
