Heidi Klum has her very own doppelganger in the form of her brother-in-law, Bill Kaulitz.
The Tokio Hotel frontman was mistaken for the German supermodel at the season three premiere of his and his twin brother, Heidi's husband Tom Kaulitz's, Netflix series, Kaulitz & Kaulitz on July 22.
Bill turned up to the red carpet alongside Tom wearing a see-through dress over black shorts and knee-high boots, with tumbling blonde waves and bangs, just like Heidi.
The uncanny resemblance to his sister-in-law didn't go unnoticed by fans, Heidi, and her famous friends.
Taking to her Instagram Stories, Heidi shared a screenshot of her conversation with Sofia Vergara, who sent her a photo of Bill and Tom along with the message: "He is your twin not his."

"He morphed into me in the last few years but I take it as a compliment," she added.

A second said: "Heidi's sister?" A third quipped: "Heidi and Tom how beautiful." A fourth added: "Bill looks like Heidi. I am confused."

Inside Heidi and Tom's age-gap marriage
Heidi, 53, and Tom, 36, have been married since 2019 and don't let their 16-year age gap get to them.

"Now they're 19, 18, 17 and 14," Heidi said at the time. "So I feel like the days of me going to bed at 9.30 are kind of over."
She explained: "When you have four kids, they keep you up day and night because trust me, with four, there's always one, either [one] has a fever, the next one has a bad dream, there is always something going on.

Speaking of their age difference, Heidi previously told Glamour Germany: "I'm 50 and no longer 20. I'm not a young girl who hasn't experienced anything yet or has no idea about life.
"Time won't stand still for me, and Tom will never catch up with me. I'll always be 16 years older, and I'm aware of that."
© Getty ImagesHeidi also says that it is just a fact of life that she will "look older than him sooner."
"Maybe it will be a problem for me in 10 years’ time, maybe he won't like it then," she remarked. "In 20 years, I’ll be 70. I usually plan for the future – but with my husband, I live in the here and now."
