Seal is Cassian Grantstanding by his daughter Leni Klum.

The "Kiss From a Rose" singer recently reflected on his bond with the 19-year-old, whom he shares with ex-wife Heidi Klum, while sharing a sweet snap with his arm around Leni as they grinned for the camera during an outing in New York City.

"In NY with the young woman who changed my life for the better 19yrs ago," the 60-year-old captioned the Sept. 4 Instagram post. "Thank you Leni for making me a better person. Love you, -papa."

Leni commented back beneath her dad's kind words, writing, "so cute! i love you papa."

But the "Crazy" artist is no stranger at showcasing his love for his eldest, as back in March he praised the model as she follows in her supermodel mom's footsteps.

"I'm so proud of everything that Leni has done," Seal told Justin Sylvester and Adrienne Bailon Houghton on E! News at the time."But I'm more proud of everything that she is."

He added, "She walks through life with this type of humility that allows her to move so gracefully through it all and she has an innate understanding of people in general and people's feelings. So I'm kind of more impressed with everything that she is."

Seal—who is also dad to Henry, 17, and Johan, 16, with Heidi—reflected on co-parenting Leni with the America's Got Talent judge throughout the years.

"I'd like to think, as a parent, that we have—between her mother myself—that we've instilled some of that in her," he continued. "But she can do no wrong in my eyes and she's quite wonderful."

Heidi—who has since found love with Tokio Hotel rocker Tom Kaulit—has also chimed in on her daughter's budding modeling career, after the two teamed up in a photo shoot, for an Intimissimi lingerie ad campaign in 2022.

"I'm very proud of my daughter and her modeling," Heidi told People in March. "And she's studying at the same time, she's juggling already."
