Strike a pose: Beyonce slipped into a deeply plunging peach silk dress as she continued her stay on Jeff Bezos’ $500 million mega yacht with Jay-Z and Blue Ivy on Monday

She also flashed her cleavage in another outfit – a loosely-buttoned white shirt, with a layering of necklaces beneath in rose gold.

Beyonce has been documenting the trip on the boat with her loved ones as they continue to sail the Med.

She looked chic sipping on a cup of tea overlooking the crystal blue waters off the Italian coast in another snap.

American entrepreneur Bezos’ yacht cost him a reported £354m but, with running costs, has set him back £500m.

During the boat’s construction, leaked plans from Netherlands-based manufacturer Oceanco hinted that it was based on the Black Pearl – the world’s largest and most technically advanced yacht.

Known only by its project name, Y721, it is said to be 127 metres, features multi-decks, is run via three giant masts, and even has a separate support yacht for him to land his chopper.

The yacht features a pool and cinema room, among other amenities.

Bezos – whose fortune is around $200 billion – also has to foot an estimated $50million on annual running costs.

Beyonce and Tiffany recently came under furious fire over the decision to showcase the controversial diamond, with many social media users calling attention to its contentious history and the circumstances under which it was mined.

According to a source close to Beyonce, the singer was unaware of the diamond’s controversial history, and has been left outraged over the fact that she was not given more information about the gem’s background.
