Boris Becker, 33, who's been in the news over his acrimonious custody battle with ex-wife Barbara, 33, over their children, Noah, 6, and Elias, 1, is in the headlines again -- this time with the announcement on Wednesday that he's fathered a baby girl with a Russian model living in London, reports the Associated Press. The retired tennis star (a three-time Wimbledon champion) admitted Wednesday that he's the father of a 10-month-old girl by Angela Ermakova, 33. "I acknowledge the fatherhood. I take the responsibility and will provide for little Anna," he said in a statement released by his spokesperson in Munich. "Whatever I can contribute so that Anna will have a future as a happy girl, I will do." His paternity was proven by a test demanded by Ermakova. The legal proceedings for the paternity case began on Monday in London, but it's unclear whether the model will go ahead with the suit.
