She has joined her billionaire pub baron boyfriend Justin Hemmes for a lavish getaway in Croatia. 

And Madeline Holtznagel was dress to impress on Wednesday as the couple enjoyed a cruise on a private yacht with friends.

The model, 26, flaunted her incredible figure as she posed in a skimpy blue bikini.

On Thursday, she shared a carousel of snaps of her sunning herself on the luxurious vessel.

Madeline showed off her washboard abs and fit physique as she posed in the two-piece, which was adorned with giant roses.

She paired her swimwear look with cat-eye sunglasses, gold hoops and a straw sun hat. 

She kept her long blonde locks down and straight as she opted for minimal makeup for her day out on the water. 

Friends and fans of Madeline jumped to the comments of the holiday snaps. 

Nude artist Dina Broadhurst wrote: ‘Last pic are you kidding’ followed by three flame emojis.

This comes just days after Madeline and Justin enjoyed a trip to Japan.

In one photo, Madeline teased her followers by wearing a ring on her wedding finger while cuddling up to Justin as they enjoyed a bowl of Udon noodles together at a restaurant.

The bling appeared to be a pretty turquoise dress ring she teamed with her outfit.

Another photo saw her wearing a different ring on the same finger as she posed in front of a bathroom mirror for a selfie.

The couple were all smiles in the photos, looking happy in love.
