How can you blame a guy who was born to run?

Bruce Springsteen was carrying on an affair with a married woman, Ann Kelly, in New Jersey, according to more divorce papers filed by her soon-to-be-ex-husband, Arthur Kelly, the New York Post reports.

News of the alleged affair first surfaced in 2009, when Arthur Kelly named Springsteen as the other man in court papers. According to court documents, Ann and Bruce met at a gym in New Jersey in 2005, when Bruce allegedly went after her as she ran on the treadmill – telling her she had the “nicest (er, glutes)” in the gym.

Her husband claims in the divorce docs that Bruce and Ann began going to lunch, and it eventually became a full-on affair. Bruce even became the main topic of conversation in marriage-counseling session between Ann and her hubby, the papers say. It got so hot that in 2008, Ann allegedly was seen with Springsteen while her husband underwent open-heart surgery in Cleveland. Springsteen has been married since June 1991 to Patti Scialfa, whom he started an affair with while married to his previous wife, Julianne Phillips .
