She’s rumoured to have invested in ‘subtle’ cosmetic procedures over the years in a bid to maintain her age-defying appearance.

And Getaway host Catriona Rowntree, 47, looked remarkably youthful on Tuesday, during an interview on Channel Nine’s Today show.

Speaking from Melbourne’s Rod Laver Arena, the glamorous TV presenter showcased her radiant complexion and wrinkle-free skin.

Catriona, who has been nicknamed ‘Australia’s most-travelled woman’, appeared on the Today show to promote her new book, The Best of World Cruising.

The book is billed as the ultimate bible for people considering cruise ship vacations. 

During her interview, Catriona perfectly complemented her luminous skin with a light makeup palette and styled her blonde hair into loose waves.

It comes after Catriona’s age-defying beauty was called into question last year by a celebrity plastic surgeon.   

In August 2018, Beverly Hills-based Dr. Randal Haworth offered his expert opinion on how Catriona has maintained her youthful complexion over the years.

‘It is only on close inspection that clues arise as to what she may have done to keep her appearance polished,’ he observed.

Catriona, who looks like she has hardly aged since starting her TV career in her twenties, has never confirmed or denied having Botox or fillers.

But according to Dr. Haworth, who has not treated Catriona himself, there are tell-tale signs that suggest she has had ‘subtle’ procedures to her face.

‘Over the years, Catriona is, what I call, a perennial beauty. Starting off as a radiantly attractive woman, any aesthetic procedures she receives must be subtle and “under the radar”, so to speak,’ he explained.

‘It seems that she hasn’t aged one iota since the 1990s,’ Dr. Haworth added.

‘Certain natural wrinkles, such as the crows feet and the horizontal lines of the forehead, are noticeably diminished while wrinkles are present in the immediately adjacent areas.

‘To me, this indicates that Catriona has had Botox.’

Daily Mail Australia has contacted Catriona Rowntree for comment.

Dr. Haworth’s claims come after Catriona revealed her strong thoughts on Botox and fillers in an interview with Who magazine in July last year.

‘Whatever floats your boat, but don’t distort your facial features with plastic surgery and try telling me that beauty comes from within,’ she said at the time. 

She also criticised people who refuse to admit they have had cosmetic work done, adding: ‘I won’t stand for it!’
