Jeff Bezos and fiancée Lauren Sanchez are continuing their Mediterranean summer tour, stopping off on Wednesday evening in the Croatian city of Dubrovnik with friends Katy Perry, Orlando Bloom and Usher.

The group was seen strolling the picturesque limestone-paved streets of the historic walled city, enjoying the early evening light.

Accompanied by socialite and influencer Derek Blasberg and protected by security guards keeping curious tourists away, they ambled along the Stradun – the pedestrianized main street, flanked by restaurants, bars and shops.

Sanchez, 53, donned a green skirt by Berlin-based designer Ottolinger for the outing, with a black crop top and gold Grecian-style sandals.

The ‘painterly-print recycled-polyester maxi skirt’ retails for $400.Her 59-year-old boyfriend and Amazon founder was dressed down in white chinos and a navy T-shirt.

White outfits were evidently in favor: Bloom, 46, was in an all-white shorts, T-shirt, waistcoat and baseball cap combo, while his songstress fiancée was in a white crochet dress, accessorized with a brown Hermes mini Kelly bag, which sells for between $7,000 and $50,000.

Perry, 38, wrapped up the first part of her Las Vegas residency on August 13, and will return to Resorts World for another series of shows in October and November.

Bloom was due to be shooting the boxing film The Cut in Nevada this summer, but the Hollywood actors’ strike has seen him and others cease work, and the industry grind to a halt.

Usher, meanwhile, will play a show in Paris in September before joining Perry with his own Las Vegas residency.

The 44-year-old Texan was flamboyantly dressed in a green patterned silk shirt with white pants.

His music executive girlfriend, Jenn Goicoechea, with whom he shares two children, was nowhere to be seen.

The group sailed up to the dock and used to ferry passengers from the 417-foot Koru, where they are based.
