Lance Bass thinks people should "listen" to Britney Spears.
The 'Toxic' hitmaker has been under a conservatorship since 2008 and in November, her application to have her father Jamie Spears suspended as the person in charge of her estate was denied, though financial company Bessemer Trust were appointed co-conservator.
And her old friend thinks the 39-year-old star's views ought to be taken into account and people should take notice if she has an issue with her dad being in control of her affairs, though he admitted he has no direct knowledge of the situation.
Speaking to Australia's 'Today Extra', he said: "We should definitely listen to her, and if she wants out of this conservatorship with her dad controlling it, then we should listen to her.
"I don't know the specifics of her situation and if she should be out of a conservatorship. But the thing I've told the fans out there is I don't know. I have no idea what's really going on."
But the former 'N Sync singer insisted he would support whatever arrangements are in place - if Britney's younger sister, Jamie Lynn Spears, is "cool" with them.
He added: "I do trust her sister, Jamie Lynn [Spears] and as long as Jamie Lynn is cool with whatever she's doing, I mean, I have to be."
The 41-year-old star admitted his own experiences of being in the public eye are very different to those of the 'Gimme More' singer.
He said: "Being a female is definitely different. Being at such a young age. Also I had my best friends in my group, so it was easier to deal with. She was just a solo act.
"She had everything riding on her shoulders, the whole world was either against her or for her and that's a lot to take in."
Although Jamie Lynn hasn't addressed the situation surrounding the conservatorship directly, she recently praised her sister for her positive attitude.
She said: "I think that she's doing just like the rest of us. She's trying to make the best and stay positive during a very challenging time and challenging year, and I think that that's kind of the theme of everyone right now."
