Adele is saying hello to a new relationship … and some chic couture.

In a slideshow post Sunday, the singer stunned in Schiaparelli couture while making things Instagram-official with boyfriend Rich Paul

She marked the major milestone in style, sporting a custom off-the-shoulder black dress featuring white silk taffeta “rosette” sleeves. 

Captioned simply with a heart emoji, her photo dump featured several solo shots of her outfit, before ending on a black and white photo of her and Paul. 

Adele, 33, accessorized the curve-hugging column dress with equally eye-catching accessories, donning dangling Schiaparelli “tooth” earrings.

Schiaparelli has certainly given us a lot to sink our teeth into lately, as the label is behind headline-making pieces ranging from Lorde’s gold breastplate to Lady Gaga’s inauguration brooch.

Their celeb-loved designs often feature surreal, human body-inspired elements, such as Bella Hadid’s golden lungs necklace at the Cannes Film Festival and Lizzo’s large ear cuff for her “Rumors” cover art.

After months of public appearances together, Adele made things Instagram-official with NBA agent Rich Paul. Instagram

Adele’s glamorous Instagram post comes shortly after she was spotted wearing a miniskirt for a date night with Paul, 39, in Los Angeles last month.

The pair first sparked dating rumors in July when they sat together at Game 5 of the NBA Finals, just two months after Paul – whose clients include LeBron James — mentioned he’d been “hanging out” with the pop star. Following the outing, multiple sources exclusively confirmed the relationship to Page Six.

Adele finalized her divorce with ex-husband Simon Konecki, with whom she shares 8-year-old son Angelo, in March, nearly two years after separating.
