R. Kelly's lawyer has spoken of his relief after the star was acquitted of child pornography charges on Friday.

Defense lawyer Sam Adam Jr. insists he always knew the singer - real name Robert Kelly - was not guilty of 14 counts of child pornography charges and is delighted with the verdict.

He tells MTV.com, "This has been wild. It's something we've been working on for six years, and to see something come together after six years of work, when we knew that Robert was not guilty, it's just wild."

Adam also admits Kelly was nervous throughout the trial and was worried about how he would be perceived in press reports.

He says, "Robert sat there stoic throughout the trial, because he knows everyone was watching him. If he smiles, it becomes, 'He doesn't take it seriously.' If he doesn't, it's, 'He's too serious, he must be guilty.' So the best (response) that he had was to turn to me. And I was just glad to be able to give him everything I could."

Meanwhile, Adam has slammed Jim DeRogatis - the Chicago Sun-Times reporter who handed authorities the videotape - for failing to take the stand.

The journalist refused to give evidence at the trial and cited the First and Fifth Amendments as his reasons for not testifying.

Adam says, "Mr. DeRogatis said everything he needed to say when he said, 'I take the Fifth'. If he's really interested in getting out here and making sure justice is done, you get on the stand and say what's important, and he chose not to. And I ask you to ask him to explain it."
