Meanwhile, the Spring Breakers star told Humans of NY at the star-studded event that her mother taught her never to take her success for granted, so she thinks she would be okay if she lost everything.
As the internet started getting flooded with photos of Gomez and Abel at the annual fund-raising gala, some of their fans also shared several images of them on social media.
Weeknd has been dating Selena since January shortly after he split from ex-girlfriend Bella Hadid.
Just past year Bella and The Weeknd had attended the Gala as a couple.
Selena Gomez would be content if she wasn't famous tomorrow. "I wanted the look to be something different than anything I had worn in the past".
The 20-year-old model wore a revealing catsuit designed by Alexander Wang.
Gomez has always been close with her mother, Mandy Teefey, so even though she's a fully-grown adult, I imagine her mom's approval still means a lot to her.
Once inside the Gala, Hadid headed for a bathroom break but ended up sitting on the floor and breaking the rules. "Mama is happy XO", she wrote in the comments section of an Instagram photo shared by The Weeknd.
While it's been just a couple of weeks since the couple made their official Instagram debut on each other's accounts, the lovebirds have been getting cozy in almost every corner of the world since January. Shortly after reports of The Weeknd's new romance surfaced, the model unfollowed Gomez on Instagram.
After a months of playing coy and a handful of social media selfies, the pair went all out at the high-fashion event on Monday night in NY. In March, she joined him in South America, posting videos of the crowd from her VIP seat at his Brazil show.
The 24-year-old singer adorned a custom-made Coach gown with ornate embroidered detail to the star-studded bash, which took place in NY last Monday (01.05.17), and the fashion label's creative director Stuart Vevers has revealed the "Kill Em With Kindness" singer was the "starting point" for the creation, and their interest in the "cool, feminine" era also influenced their style choices for the event.
