Hilary Duff swaps cars to fool paps

Hilary Duff says she has come up with tricks to escape the paparrazzi.

The 26-year-old singer, who has just released her first new music in seven years, said photographers follow her around for about 11 hours every day.

"They tend to be there from 7.30 in the morning to about 6 at night," Duff told AAP from a hotel room in Sydney on Wednesday. The singer is in town to promote her new single, All About You.

She says she ducks down in her car, or takes a different car to avoid the photographers..

"When I was pregnant and about to have my baby they were relentless, they were outside the house at all times.

"So I would rent a car and the second they would find out that car, I would swap it for a new rental," she says.

Duff is a graduate from the Disney camp - making the transition from child star in TV show Lizzie Maguire to adult actress and pop star without tarnishing her image.

Unlike her twerking Disney alumna, Miley Cyrus, Duff managed to stay wholesome as she took parts in films such as A Cinderella Story (2004) and then adult parts in War,Inc (2008) with actor John Cusack.

The singer is now mum to a two-year-old son, Luca, who she had with her husband former NHL player Mike Comrie - the pair are now separated .

She says nearly every moment of her day is snapped by waiting photographers.

Day to day events become major moments.

"I'll be feeding a meter and they (paparazzi) will be like 'over your shoulder' and I'm like 'I'm not on a red carpet right now, I'm on the street feeding my meter," she says.

"And I'm in my exercise clothes almost every day, how interesting is that?"

It's no surprise she wants her son to have a more normal life and would prefer if he didn't go down the showbusiness route.

"I will try to encourage other things. I'm not sure if I had my way I would choose it for him," she says.

Duff is returning to the pop charts after a seven-year hiatus from music. It's a long break, but she says after touring straight from the age of 15-20, she needed that time.

"I just kind of felt like every single one of my days was scheduled out for me and everyone was deciding what I did every single day," she says.

After a break, longer than she anticipated, Duff feels she now has something to say - or enough to get her back into the recording studio.

While her last album, Dignity, was more of a dance record, Duff is taking a folky-route on her upcoming pop record.

But the music scene has become even racier than when Duff last released a record. There are more twerking bootys on stage now than there are perfect pop princesses. And Duff still has one of the more wholesome images in pop.

But that's not something that's about to change anytime soon.

"I've a two-year-old, I'm not going to go nudie any time soon ... I'm not going to take my tops off and be naked in videos," she says.
