The 26-year-old Victoria Secret model and actress was the star guest at a lavish launch party at Hayman Island resort, on Wednesday night.

The brand has Australian ambassadors Dannii Minogue and Cheyenne Tozzi, but recruited the English model in an attempt to take on international beauty giants such as Max Factor, L'Oreal and Maybelline.

"Whilst ModelCo is an Australian brand it has global distribution and Rosie resonates with our customers," says Shelley Barrett, ModelCo CEO and founder.  "With her busy lifestyle she epitomises a busy girl on the go."

Swamped with beauty offers Huntington-Whitely says she decided to sign with ModelCo because she knew the hot pink branded products.

"I bought ModelCo's Tan In A Can from Boots [London based pharmacy] and I really liked it.  It's a brand all my friends know about and use.  It's cool. I like that it has products that are dual purpose," she says.

"I like how cool it is to have the lipgloss that has a mirror and light attached," she says.

And for a pretty penny she shares her product endorsement with her fans. 

With over 750, 000 followers on Instagram and 275, 000 followers on Twitter the behind the scenes photos she's been posting of the shoot have been getting tens of thousands of "Likes".

Her presence has already stirred international attention with paparazzi sneaking on to the island and attempting to hire helicopters to get snaps of the star.

Seventy people attended the black tie event which was themed with a touch of pink.  Even a hot pink carpet was flown in for the night.

Huntington-Whiteley wore a white Calvin Klein dress revealing her midriff and accompanying belly jewellery.

"I've had such a lovely couple of days here.  It's been like a dream," she told the guests.  "I certainly hope I will be back."

Huntington-Whiteley, who is also known for her role in Transformers: Dark of the Moon, has been dating actor Jason Stratham for the past three years.  In the past few days rumours have been flying around the globe that he's set to propose soon.

When asked about it she says, "I woke up to those stories yesterday.  It's ridiculous what they write.  I don't pay any attention to them."

Then she coyly adds, "But it would be exciting."
