Leni Klum has been pictured with her biological father Flavio Briatore and half-brother Nathan Falco, 13, in a rare family photo.

Heidi Klum's model daughter, 19, was seen posing on a yacht in an Instagram photo taken during her August trip to Italy, proving that she has reconnected with the Formula One boss, 73. Leni was adopted by Heidi's now ex Seal when she was just five years old after coming to a mutual agreement, and when quizzed about his biological daughter in 2016, Flavio famously said, "it's hard to miss a baby you never see".

But now, in unearthed photographs shared on his Instagram account – liked by Heidi herself – Flavio is seen spending quality time with Leni in his home country.

Another sweet image sees the model and her half-brother Nathan, Flavio's son from his marriage to actress Elisabetta Gregoraci, enjoying a picnic with their father.

It appears Heidi, who is happily married to Tokio Hotel guitarist Tom Kaulitz, was also present on the trip as she spent much of the summer sharing envy-inducing bikini photos from her Italian vacation.

HEIDI AND SEAL'S CHILDREN

Leni, now a successful model, grew up in LA while Flavio was based in London. TMZ first reported in 2018 that Leni and Flavio had reconnected with the help of her parents, but the pair hadn't been pictured together until now.

What happened between Heidi Klum and her ex Flavio Briatore?

Heidi and Formula One boss Flavio began dating in March 2003, however, they split shortly after she announced her pregnancy in December of that year.

By the time Heidi welcomed her firstborn Leni in May 2004, she was loved up with musician Seal. The Kiss From a Rose singer went on to officially adopt Leni when she was five years old and her name was legally changed to Helene Samuel.

Heidi and Seal went on to have children Henry, 16, Johan, 14, and Lou, 12, and the pair have remained very close friends since their amicable split in April 2012.

In a rare interview about Leni in 2016, Flavio told Italian newspaper Corriere Della Sera that he had "calmly" reached the decision with Heidi and Seal at the time.

"The three of us calmly agreed that it made the most sense that he adopt her, because a child needs to grow up in a family," he said, adding that they all had an "amazing" relationship.

He also made clear that he had tried to stay in touch with Leni, despite the "unbridgeable" distance, revealing they used to speak on the phone daily.

"Leni was born when Heidi and I had already spilt. Heidi was living in Los Angeles and I was in London, the distance between us was unbridgeable," he said.

"We used to speak on the phone two hours a day, but it wasn't enough. She needed to stay with her mum."

He added: "It's hard to miss a baby that you never see. But I know that Leni is not an abandoned child. Leni is part of Seal's family and Nathan is part of mine."
