Beyonce and Jay Z's luxury Italian getaway rolls on with a stop in Sardinia… but why do they look so miserable again?

They've been relaxing on a yacht and exploring the stunning sights during a luxurious holiday in Italy.

But once again Beyonce, 34, and Jay Z, 46, failed to crack a smile while soaking up beautiful Sardinia on Wednesday.

The A-list couple have spent much of their expensive vacation looking miserable, and it was no different on this outing as they silently strolled hand-in-hand through Porto Cervo. 

Beyonce had earlier been seen looking bored while texting on her mobile phone as she and Jay Z headed into the seaside resort on a boat.

It comes after the singer and the rapper, whose four-year-old daughter Blue Ivy has joined them on the trip, were spotted apparently in the middle of a tense discussion as they made their way to dinner over the weekend.

And even a jet ski ride wasn't enough to raise a grin out of Jay Z, who remained stony-faced as he zipped across the water.
