Bella Thorne put on a seriously sizzling display as she enjoyed a sun-kissed getaway to Italy with her fiance Mark Emms.

The star, 25, risked a wardrobe malfunction in a very skimpy triangle bikini as she packed on the PDA with her hunky future husband.

She left very little to the imagination as she basked in the sunshine in a string swimsuit with an arty blue design.

The couple, who announced their engagement in May, could hardly keep their hands off one another as they enjoyed some quality time together by the shore.

Mark wrapped Bella up in his arms from the behind as he lavished her with kisses.

She tenderly placed her hand upon his head as he gave her cheek a peck.

The couple looked totally lost in each other as they flung their arms around one another, completely tuning out the beach full of visitors.

The beauty was a vision of summertime glam in her sexy look.

She rocked a chunky gold necklace with a heart, a slew of rings, and edgy sunglasses. A bold red slick of nail polished adorned her nails, and she also tossed on a semi-sheer white top over her swimsuit.

As for Mark, he sported a black T-shirt and colorful shorts.

Once they were all done for the day, Bella tossed on a pair of slouchy trousers, a floppy hat, and sandals.

She carried her belongings about in an ultra chic woven Loewe tote.

Bella reached for her love as they departed the beach, before he placed his hand upon the small of her hand.

Later, Bella shared a mirror selfie snap with her sister, Dani, and their friends as they showed off their beach day ensembles.

She also shared a zoomed-in shot showing off her outfit details and, at the same time, her stunning figure.

The Midnight Sun actress announced her engagement to Mark, an entrepreneur and producer, in late May.

The couple met last year on the beach in Ibiza at Cara Delevigne’s birthday party.

‘It was love at first sight as the sun rose,’ the American Horror Stories star told Vogue Weddings.

The Imagen Foundation Award winner and her fiancé also posed together in a sweet photo announcing the news on social media.

Bella made sure to included the 10-plus carat emerald cut diamond engagement ring prominently in the photo.

The couple had been keeping the secret for a while.

Mark, who also owns the New York City hotspot The Mulberry, actually popped the questions at Bella’s house in California on Mother’s Day.

The Divinity star told the publication she’d like to have the wedding at a country manor in the United Kingdom, but has not announced a wedding date.

The bride-to-be did reveal that she is looking for more than one look for the big day, with an eye toward vintage Schiaparelli or Dior.

‘Every bride does not need one gown,’ she said hinting at multiple wardrobe changes, ‘but four!’

The busy actress has a slate of projects on her roster, including the upcoming Saint Clare.

The horror-comedy focuses on a quiet college student with a ‘divine vocation for killing,’ according to the movie’s description on IMDB.
