Jude Law has reportedly apologized to his family after DNA tests "conclusively" prove he has fathered another child.
The 36-year-old actor has been officially told that he is the father of Samantha Burke's daughter Sophia, who was born last month following a brief fling with the aspiring actress.
Samantha's agent Eileen Koch said: "Samantha can confirm that DNA testing has conclusively established that Jude Law is Sophia's father. Check back in six months. Maybe she and Jude will be getting married."
Jude now faces paying maintenance for Sophia's upbringing, which experts expect will total over $3 million, prompting the 'Sherlock Holmes' star to reassure his children Rafferty, 14, Iris, eight, and Rudy, seven - his kids with former wife Sadie Frost - that the news will not affect his relationship with them.
A source told the Mail Online website: "He told Sadie that he only slept with her once. But now he has confirmed to her and his children that the child is his. He has reassured the children it will not affect their family times together."
Another source added: "Sadie is livid. She feels that he has put unnecessary pressure and upset on to the children and has put himself under financial strain, which impinges on their life."
A spokesperson for the star said she was aware of the DNA test statement but refused to comment further.
She said: "We don't discuss this. We consider it an entirely private matter."
Jude and Sadie divorced six years ago, but remain close friends.
The actor met Samantha, 24, while he was filming in New York late last year.
A few months later, she phoned to tell him she was pregnant.
