Her most recent public reunions with Krost appear to have been back in 2019 and 2021, though a source told Entertainment Tonight on Sunday that the Spring Breakers star is only focused on ‘casually dating’ at the moment.

She was pictured descending a set of steps leading out of the venue, with multiple men in suits and tuxedos following behind her.

Back in black: Selena Gomez was looking effortlessly elegant in an all-black ensemble when she attended the wedding of her ex-boyfriend Samuel Krost on Sunday

Old friends: The 31-year-old singer and actress showed she was still on good terms with Samuel, who is a fashion label founder and a talent booker for the doomed Fyre Festival scam, as he tied the knot with Esther Shemia at a chateau in Condecourt, France

Selena was covered up in a modest black maxi dress that reached down nearly to the ground and was styled loosely enough that she had to grasp at the dress as she walked to avoid tripping on it.

Atop the dress was a luxurious black fur coat that shimmered in the modest light, though it wasn’t clear if it was made of real or faux fur.

The 5ft5in beauty stood tall in a set of black open-toe stilettos that strapped around her ankles, and she had her long caramel-highlighted hair styled in a bun with remaining wavy strands draped over her back and shoulders.

Selena was impeccably made up with a mauve lip and a delicate smoky eye.

She accessorized her look with a glittering silver handbag featuring an asymmetrical swoop at the top.

The hitmaker could be seen chatting with a female pal as she stepped out of the venue into the courtyard outside.

Her ex Samuel spiced up the standard tuxedo with a lustrous double-breasted black satin jacket and a particularly floppy bow tie.

Esther looked stunning in her white wedding gown, which featured multiple layers of carefully detailed lace.

The bride had a delicate sheer bodice and more lace around her neck, as well as a white veil covering her face.

She held a bouquet of pale pink flowers as she was seen descending a set of stairs with multiple attendant to hold her dress up.

She appeared to be focused on comfort for part of the day, as she was seen walking around in her full gown with what looked like brilliant white sneakers.

Later, the brunette beauty showed off her eat-to-ear smile as she waved down at her friends and family from a window of the chateau.

Samuel and Selena appeared to keep their time together fairly low key.

The former couple fueled relationship rumors when they were pictured holding hands back in 2015, but Selena never commented on the relationship.

The following year, Samuel wrote a since-deleted Instagram post that seemed to confirm the relationship, though it appeared to be behind them at the time.

‘Selena is a real girl with a real heart and real feelings. All you superficial who are just unhappy with your love lives, understand that love is real,’ he wrote. ‘Although we have ventured on separate paths, at least I know that love exists. I love you, Sel.’

Krost’s relationship with Gomez was the first time he came to the attention of many of her fans, but he would subsequently be connected to the infamous Fyre Festival after he admitted that he had been hired to book musical acts for the event.

However, he is also known for founding a fashion label.

The couple were spotted together again in 2019, and again in 2021, though that time she clarified on social media that she was not dating anyone.

Although Selena was celebrating her good friend’s nuptials, she doesn’t appear to be circling around a serious relationship at the moment.

On Sunday, a source close to her told ET that she was keeping her dating life casual at the moment.

‘Selena is casually dating and doing well,’ the insider claimed. ‘She is doing her own thing and doesn’t feel any sort of pressure to be in a relationship. She is just focusing on what’s best for her right now and has been very in tune with maintaining her own boundaries. Her friends and family support her and just want her to be happy.’

She has certainly intrigued fans and created relationship speculation after she was spotted hanging out with The Chainsmoker’s Drew Taggart earlier this year.

She was also seen holding hands with former One Direction member Zayn Malik in March, and the two even kissed while dining out, setting off new relationship rumors.

Afterparty: Later on Sunday, Selena celebrated in Paris and shared a very busty view of her black tweed Valentino blazer dress to Instagram

However, she later (again) announced that she was single on social media, and in June she appeared to have unfollowed Zayn, indicating that nothing more was going on between the two.

Following the fairytale wedding, Selena was seen stepping out in Paris to celebrate.

She put on a particularly busty display in her black tweed blazer dress from Valentino in a photo she shared to Instagram.

The image also highlighted how she had changed up her hair by swapping out her usual raven tresses for her new lighter look.
