Jude Law is the father of an aspiring actress' child, DNA tests confirm.

The British actor had a brief fling with Samantha Burke last year, and she gave birth to a baby girl last month.

Burke's agent said, "Samantha can confirm that DNA testing has conclusively established that Jude Law is Sophia's father."

Law, who may have to pay up to £2 million maintenance for the child's upbringing according to experts, has reportedly reassured his three children that he has with his ex-wife Sadie Frost that this will not change his relationship with them.

An insider told the Daily Mail, "He told Sadie that he only slept with her once. But now he was confirmed to her and his children that the child is his. He has reassured the children it will not affect their family times together."

Law's spokesperson added, "We don't discuss this. We consider it an entirely private matter."
