Conor McGregor put on a smitten display with his fiancée Dee Devlin as they enjoyed a sun-filled boat trip.

The Irish professional mixed martial artist, 33, cuddled up to his partner, 34, as they relaxed on a lavish boat in snaps shared to Dee’s Instagram on Monday.

Conor showed off his muscular frame as he posed shirtless with his arms wrapped around Dee as they took selfies while soaking up the sun.

Other snaps also showed Conor lying across his fiancée as he wore a blue patterned shirt during their luxurious trip.

Meanwhile, Dee flaunted her incredible physique in a vibrant red two-piece, which she teamed with a pink patterned sarong fastened around her waist.

She simply captioned the sweet snaps with a love heart emoji as she gushed over Conor, who she shares children Conor Jr, five, Croia, three, and Rían, one, with.

Commenting on the post, Conor cheekily wrote: ‘Get cosy baby.’

The couple appeared to be as smitten as ever after cementing their love for one another by getting engaged in 2020 after 12 years of dating.

Conor has been making the most of his £2.4million Lamborghini super-yacht as he spent time on the vessel while in Monaco for the F1 Grand Prix last month.

He shelled out more than £2million for the Lamborghini yacht, one of only 63 to be built by the Italian manufacturer, in October.

His boat is understood to be the twelfth off the production line, a tribute to his whiskey brand, Proper Twelve.

But the price is a mere drop in the ocean for the sportsman, who has an estimated net worth of £145 million.

The Tecnomar 63 has been designed and built by the Italian Sea Group and Tecnomar for Lamborghini.

At 24 tons, the 63-feet long yacht can reach a top speed of 69mph (60 knots) and boasts 4,000 horsepower with its twin 24.2-litre V-12 diesels.
