Heidi Klum's Daughter Leni Meets with Biological Father, Flavio Briatore

The baby daddy of Heidi's Klum's oldest child, Leni, has not been a part of her life for years ... but it looks like that's changed after a reunion in Italy.

The biological father of Heidi's 14-year-old daughter is Italian businessman Flavio Briatore ... but the couple split before Leni was born in 2004, so she was was adopted and raised by Klum's ex-husband, Seal.

Heidi and Flavio have long stated he has no involvement in Leni's life, but something apparently changed recently ... as the father/daughter met and embraced at the Cala di Volpe hotel in Porto Cervo late last month.

We're told Heidi was there with her entire family, including her parents and her 3 other kids ... and everyone was happy and having fun. Flavio joined them all for a meal and was seen chatting with Klum as well.

It's unclear at this point if this was a one-time special occasion, or if Leni's father plans to see her more regularly.
