CHICAGO >> R. Kelly angrily blamed his ex-wife for “destroying” his name and claimed other people stole from his bank accounts during new portions of an interview that aired today, a day after the R&B star was jailed for not paying child support.

Kelly, who is charged with sexually abusing three girls and a woman in Chicago years ago, shouted and cried as he spoke with Gayle King of “CBS This Morning.” He said his ex-wife was lying when she accused him of domestic abuse, and his voice broke as he asked, “How can I pay child support if my ex-wife is destroying my name and I can’t work?”

The 52-year old singer was jailed Wednesday after he said he could not afford to pay $161,000 in back child support. He said he had “zero” relationship with his three children but knows they love him.

The interview, which was recorded earlier this week, marked the first time Kelly has spoken publicly since his arrest last month in the sexual abuse case. In segments that aired Wednesday, he ranted while pleading with viewers to believe that he never had sex with anyone under age 17 and never held anyone against their will.

The interview also marked the first time he addressed allegations in the Lifetime documentary series “Surviving R. Kelly,” which aired in January and alleged he held women captive and ran a “sex cult.”

Experts said Kelly’s appearance was risky and could backfire if it gives prosecutors more information to use against him at trial. That’s why most defense attorneys urge clients to keep quiet.

“In my history as a prosecutor, I loved it when a defendant would say things or make comments about his or her defense,” said Illinois Appellate Judge Joseph Birkett, who said he did not watch the Kelly interview and was speaking only as a former prosecutor. “I would document every word they said … (and) I could give you example after example where their statements backfired.”

There have been cases in which people who spoke up pointed to evidence that ultimately helped win their freedom, but “historically it’s a bad idea,” Birkett said.

A recent example of where such an interview might have done more harm than good was in the case against “Empire” actor Jussie Smollett, who was charged with falsely reporting a racist, anti-gay attack against him in Chicago. In charging documents, prosecutors cited statements he made during an interview on ABC’s “Good Morning America” identifying two people in a photo of the surveillance video as his attackers. The two brothers pictured in the photo later told police that Smollett had paid them to stage the attack because he wanted a raise and to further his career, prosecutors say.

In Kelly’s case, he and his attorney might have decided they had nothing to lose after the Lifetime series, said Fred Thiagarajah, a prominent Newport Beach, California, attorney and former prosecutor.

“A lot of the public already thinks he’s guilty, and there is a very negative image of him, so the only thing he might think he can do is try to change their minds,” Thiagarajah said. If the evidence against him is overwhelming, “this kind of interview might be kind of a Hail Mary” to influence a potential jury pool.

But the dangers of such an interview might outweigh any benefits if Kelly locks himself into a particular defense, Thiagarajah said, adding that the star “may not know all the evidence against him.”

In the CBS interview, for example, he denied ever having sex with anyone under 17, even though he married the late singer Aaliyah when she was 15. A videotape given to prosecutors in his current case purports to show Kelly having sex with a girl who repeatedly says she’s 14. And police in Detroit were looking into a woman’s claims that Kelly had sex with her in that city in 2001 when she was 13.

Kelly’s attorney, Steve Greenberg, has said his client did not “knowingly” have sex with underage girls. He was not immediately available today to comment on the Detroit allegations.

Thiagarajah said he might allow a client to do such an interview — but only if he were confident the client could keep his emotions in check and “stick to a script.”

“If you get someone who is ranting and raving, I would never let that kind of person ever do an interview,” he said.

On Wednesday’s broadcast, Kelly’s emotions swung wildly as he explained he was simply someone with a “big heart” who was betrayed by liars who hoped to cash in.

In a particularly dramatic moment, he angrily stood up and started pacing, his voice breaking as he yelled, “I didn’t do this stuff! This is not me!” He cried as he hit his hands together, saying, “I’m fighting for my (expletive) life.”

He insisted people were trying to ruin his 30-year career, but then said his fight was “not about music.”

“I’m trying to have a relationship with my kids and I can’t do it” because of the sexual abuse allegations, he shouted. “You all just don’t want to believe it.”

Hours later, Kelly went to the child-support hearing “expecting to leave. He didn’t come here to go to jail,” said his publicist, Darryll Johnson. Johnson said Kelly was prepared to pay as much as $60,000. He said Kelly did not have the whole amount because he has not been able to work.

A spokeswoman for the Cook County Sheriff’s Office said Kelly would not be released from jail until he pays the full child support debt. His next hearing was scheduled for next Wednesday.

Kelly spent a weekend in jail after his Feb. 22 arrest in Chicago before someone posted his $100,000 bail. His defense attorney said at the time that Kelly’s finances were “a mess.”

Interviews with two women who live with Kelly — Joycelyn Savage and Azriel Clary — also are set to air. Savage’s parents insist she is being held against her will. Kelly suggested during the interview that her parents were in it for the money and blamed them for his relationship with their daughter, saying they brought her to watch him perform when she was a teenager.

A lawyer representing the couple bristled at the allegation, saying on Wednesday that Timothy and Jonjelyn Savage never asked for or received money from Kelly. The couple said they have not spoken to their 23-year-old daughter for two years. They spoke later that day.
