Their romance raised more than a few eyebrows due to their 48 year age gap.

But Don McLean's much younger girlfriend Paris Dylan, 24, appeared to put the critics to the back of her mind as she flaunted her rather ample cleavage on her Instagram.

The striking beauty has been enjoying the fruits of being on tour with her 72-year-old singer beau, not only travelling through Europe and but heating up her Instagram feed with a number of saucy selfies.

Paris, who was initially hired to manage Don's social media accounts, slipped into an busty-accentuating mesh bralet which managed to cover her modesty with a carefully placed avocado print.

She smoldered down the camera while holding onto her glossy locks in place, showcasing her taut stomach while she posed in a bathroom during their London stop last month.

In another shot, the Playboy model lamented her love for California as she slipped into a skimpy cobalt blue bikini while luxuriating in the sun.

Topping up her golden tan, she sported a pair of tie-side Brazilian bikini bottoms which accentuated her slender hips and toned midriff.

The head-turning snap only managed to show a glimpse of her delicate features as she made sure all eyes were on her enviable frame.

She simply captioned the shot: 'I love home'.

Don and Paris' surprising romance first came to light last year and the pair quickly sparked engagement rumours after the beauty posed with a large sparkler.

Paris has previously referred to herself as a 'superfan' of the folk singer and reportedly stated: 'I have to watch my Don McLean videos at least three times a day.'

A source also reported last year that the romance had been 'going on for a year' beforehand.

Paris is no stranger to life in the public eye as she has lent her good looks to a number of sexy shoots with the likes of Maxim and Playboy.

The pair's sighting comes a year after a Maine court gave Don's ex-wife an order of protection against him.

McLean pleaded guilty in July 2016 to domestic violence assault. His lawyer said at the time that his punishment would be a $3,000 fine if he stayed out of trouble for a year.

Patrisha McLean, who filed for divorce in March 2016, says she is glad the order was granted. The pair have two children, Jackie and Wyatt.

Meanwhile, Don has busy on the work front and released his new album Botanical Gardens on March 23.

The album precedes a 14-date UK tour, starting April 29 at the Southend Cliffs Pavilion. The last date will be on the tour will be on June 14 at The Marquee Cork.
