Here are five alleged celebrity fathers who answered paternity questions by submitting to DNA tests:
1. Keanu Reeves: The actor dug into his genes in 2009 after he was sued by a Canadian woman who charged he'd fathered her four children (and who he said he'd never met). The results were negative, but the woman remained positively committed to her case, accusing the Matrix master of using hypnosis to influence the test results.
2. Chris Rock: The Bring the Pain comic knows a thing, or three, about DNA. In the past decade, Rock has aced a trio of paternity tests, two to answer claims by a model with whom he had a two-night stand, and one by a freelance journalist with whom he had a "limited relationship."
3. Eddie Murphy: This star was no stranger to paternity debates—he'd faced one back in the 1980s—when he spurred an especially ugly one a few years ago, essentially breaking up with a pregnant Melanie Brown during a TV interview, and, in the same sit-down, saying he had no idea who the father of her unborn child was. Scary Spice was not amused, nor satisfied with a DNA test that proved Murphy was indeed the dad: She wanted him to acknowledge his parentage; and, finally, he did.
5. Michael Jackson: The pop star who sang "The kid is not my son" in "Billie Jean" used the refrain to defend himself in numerous paternity claims, including one from a woman who actually called herself Billie Jean. In 1994, Jackson put a twist on the DNA defense, using the DNA from the ex-husband of an accuser to show that the man, and not Jackson, was the father of the child in question.
