A US judge will decide whether R&B singer Chris Brown can perform at the Michael Jackson tribute concert in Vienna this month.
Michael's brother Jermaine recently announced that Forever singer Chris would be one of the 25 acts due to honour the late king of pop at the event, but there is now doubt as to whether he will be allowed.
The 20-year-old was sentenced to community labour last month after he admitted responsibility for the assault of his former girlfriend Rihanna.
There are reportedly concerns that the Michael Jackson concert may clash with his legal commitments.
"Chris Brown is working out some situations but he definitely expressed to us that he wants to be here," Jermaine said at a press conference on Wednesday.
"It's just up to what he's going through with his court case right now - but he's definitely going to work that out and be here."
Referring to the negative publicity surrounding the case, Jermaine stressed he was happy for the singer to take part.
"People make mistakes and he's a wonderful performer and during these times people need support and that's really important," he said.
