TAKE one teenage Romeo, add a sexy, somewhat older TV personality, mix in a little chemistry and stand back as the sparks fly.

In what might rate as the most flirtatious television interviews of the year to be aired on Channel Seven tomorrow, 19-year-old One Direction star Harry Styles charms Sunrise host Samantha Armytage - starting with a kiss and ending with a date proposal.

Armytage, 36, met Styles at Melbourne's Rod Laver Arena last week for a backstage interview joined by band mates Niall Horan and Liam Payne.

But it was the instant attraction between Styles and Armytage that had the crew talking. Even Armytage admits she was struck by the "smoothness and confidence" of her teenage paramour.

"When he walked in and kissed me on the cheek I thought; 'Oh, hello'," Armytage said, joking that her first thought was: "I am old enough to be his mother."

"But I couldn't believe that, for how young they are, they're so mature and well-adjusted and sort of much more beyond their years," she said.

"Harry was very open and talked about women. He did say he didn't care about age.

"And there was a lot of flirting from him and it wasn't just in one direction. It went in both directions."

According to Armytage, Styles suggested that she join him for a round of golf after she gave him a set of golf balls.

"He did invite me for a round of golf," she said, adding that she didn't genuinely consider the offer. "He is far too young. And I'm too old for him.

"And I prefer older men."

After the knock-back, the British heart throb was photographed several days later playing with Aussie tennis great Pat Rafter.

Armytage, meanwhile, admits she was flattered by the attention of the world's most lusted-after teen idol.

"He was very cute and seemed like a very clever boy and there is something very flattering for my ego about a guy like that flirting a little bit," she said.

While Styles has most recently been linked to 21-year-old British supermodel Cara Delevingne, he has previously been linked to several older women including UK TV presenter Caroline Flack who was 32-years old when she dated Styles, then 17.

Soon after their split Styles moved on to another 32-year-old, radio announcer Lucy Horobin who was married at the time their affair went public.
