JESSICA Simpson will be waiting in the wings when younger sister Ashlee hosts the MTV Australian Video Music Awards (AVMA's).While tonight's event will be Ashlee's first official hosting gig, Jessica's role is being kept under wraps.
"She (Jessica) is just going to be making an appearance," said Ashlee of her 25-year-old sister.
"She is going to be back there, getting my back and giving me high fives."
The sisters will walk the red carpet at Sydney SuperDome tonight, with a string of other international talent confirmed to attend, including James Blunt and Snoop Dogg.
"As far as inspiration for the show, I am just going to get out there and have a good time," said Ashlee, whose parents and managers Joe and Tina Simpson are also in Australia.
"You might see me shake my booty!"
As well as hosting duties, Ashlee will perform two songs, Boyfriend and Love.
"I just usually chill out and hang out with my band," she said of her pre-performance plans.
"I don't like to ever think too much about anything. I just like to go with it."
The Simpsons arrived in the country separately earlier this week and have wasted no time getting out and about in Sydney, having been photographed shopping in Paddington and enjoying a harbour cruise with their entourage.
Ashlee followed in Jessica's showbiz footsteps after appearing in US series 7th Heaven. She went on to release an album and has had a number of hit songs.
Jessica is best known for her starring role in the movie The Dukes of Hazzard, as well as reality TV show Newlyweds, in which she and her now estranged husband, Nick Lachey, were followed around by a television crew.
Russell Crowe and his band, The Ordinary Fear of God, will lead the Aussie contingent of artists at the MTV AVMA's.
Other locals to attend the event include the Rogue Traders, The Veronicas, Casey Donovan, Bernard Fanning, End of Fashion, Shannon Noll and Lee Harding.
Madonna hasn't made the trek Down Under but is up for the most awards, with five nominations for her album Confessions of a Dance Floor.
The Veronicas, Bernard Fanning, Green Day, Kanye West and Wolfmother are up for three awards each.
The MTV AVMA's recognise the best of Australian and international music in a variety of viewer-based categories.
Organisers are expecting the awards to be viewed by more than one billion people throughout the MTV network. Celebrity hair stylist Ken Paves says it will take him less than 30 minutes to do Jessica and Ashlee Simpson's hair for the awards.
And he promises, they will look "beautiful".
"I know the girls so well that I am really fast," said Paves, who has worked with the Simpson sisters for eight years.
"Honestly, I can get the girls hair ready in less than a half hour and they're so beautiful, they're not high maintenance divas."
Paves and make-up artist Mary Phillips have travelled to Australia with the Simpsons to make sure they look their best at the event.
Paves and Phillips other celebrity clients include Oprah Winfrey, Eva Longoria, Jennifer Lopez, Brittany Murphy, Jessica Alba and Avril Lavigne.
"These are important moments," said Paves.
"The fans look forward to them looking good. It is part of their job."
Phillips said that while the girls looked similar, their styling required a totally different approach.
"Ashlee is more rock and likes a harder, smokey eye," said Phillips.
"Jessica is the modern day Brigitte Bardot and Ashlee is like the modern day Deborah Harry."
For Ashlee Simpson herself, she says she likes to mix up her look.
"I have a hair stylist and a make-up artist but it is always kind of the mood that I am feeling," she said yesterday.
"I like to change quite a bit. I got a great team."
