Her arm tucked inside that of her new boyfriend. 24-year-old Selena looked besotted as the pair took in the sights.
The lovestruck young couple visited the Accademia Gallery Museum to gaze upon Michelangelo's David, and admire the world-famous Renaissance art on display.
The Weeknd who was previously in an 18-month relationship with model Bella Hadid is said to have been 'taken' with the Hands To Myself hitmaker when they first met at the lingerie giant's annual fashion show.
An insider claimed: 'There were sparks when they first met at the Victoria's Secret Fashion Show in 2015. They both performed and The Weeknd was just taken by Selena.'
A source said previously: 'Selena is not good friends with either Gigi or Bella. She knows them through other people, but they are just acquaintances.
'She is friendly with them, but not friends with them... Selena and Gigi were never fond of each other, so Selena definitely doesn't have any stipulations about hooking up with, or dating, Bella's ex.'
