Kanye exposed his bare bum to tourists in neighbouring boats while riding a river taxi on Venice’s famed canals – while Bianca is regularly seen wearing revealing outfits.
The source who spoke with the Sun added: “It’s hard for [Kim] because as soon as she thinks she can move on, something like this happens and she’s pulled back into it.
”It’s like every time Kanye and Bianca pull these nearly-naked stunts, it reminds everyone that Kim dressed up in skintight nude outfits during the marriage. She’d rather put it behind her and forget about it.”
Kim and Kanye have been co-parenting sons Saint, 7, and Psalm, 4, as well as daughters North, 10, and Chicago, 5, since their split.
During his bottom-baring outing, Kanye was dressed head-to-toe in his signature black, while Bianca donned a leather trench coat with little to nothing under it.
The pair “married” in a non-legally binding wedding ceremony in January, and were joined by an unidentified female friend. Kanye and Bianca got “hitched” two months after his divorce from Kim was finalised.
