Natalie Roser shows off her pert derrière in a bikini as she goes for a swim

Natalie Roser is one of Australia’s most in-demand bikini models.

And on Monday, the blonde bombshell, 33, flaunted her sensational figure during a relaxing holiday in the U.S.

In photos shared to Instagram, the model showed off her pert derrière in a skimpy bikini as she went for a swim in the Grand Teton National Park.

Natalie showed off her figure as she posed on a large rock and looked out into the distance.

‘Been offline hiking my little heart out. #jacksonhole #tetons,’ she captioned the post.

It comes after Natalie recently spoke out about her ‘unconventional first year of marriage’ with her former Home and Away actor husband Harley Bonner.

Last September, the model shocked fans when she revealed she and her husband were no longer living together in their Newcastle home.

She told the Daily Telegraph that Harley had moved to Thailand shortly after their wedding in February last year to study energy healing and meditation.

While Natalie admitted that she ‘doesn’t understand’ that world, she still supports Harley as he ‘fulfills his dreams’.

‘He is so happy. It is definitely an unconventional first year of marriage,’ she said.

‘He is fulfilling his dreams and who would I be to stand in his way of doing something that he has wanted to do for so long?’

Natalie said letting Harley travel solo in their first year of marriage was preferable to him doing it later down the track when they have children.
