Tweedy, 20, was found guilty in October of assaulting a nightclub worker - but cleared of being racially motivated.
She told BBC Radio Five Live: "I'm sorry to the fans and to my family and the other girls that it ever happened."
"I'm sorry that I went out that night," she said, adding that she had done six of her 120 hours of community service.
The singer had denied attacking toilet attendant Sophie Amogbokpa at a nightclub in Guildford, Surrey, in January.
Tweedy punched the toilet attendant after Mrs Amogbokpa tried to stop her taking some lollipops.
Judge Richard Haworth criticised her for showing no remorse and described it as "an unpleasant piece of drunken violence".
The jury found her guilty of assault occasioning actual bodily harm but not guilty of racially aggravated assault occasioning actually bodily harm.
On Tuesday, Tweedy said it was a "relief" that court case was over and a "nice surprise" that she had a positive reaction when she got back on stage.
"The fans, the girls, everyone's been so supportive, it's been unbelievable," she said. "They've took the time out to sit and write letters of support."
When asked on GMTV if she accepted her conviction, she
Tweedy said her experience of spending a night in a cell after the arrest was "awful" and a "bit surreal".
"It was like something out of a movie scene. It just did not seem real. I was in a little cell with a little wooden bench and a little sponge mattress."
She would do six or eight hours of community service a day, she added.
"That is my punishment and I am prepared to do whatever they come up with," she said.
"Once I have done my community service I will just put it all behind me and carry on."
Tweedy was also ordered to pay £3,000 of prosecution costs.
