People.com Lifestyle Style Ireland Baldwin Defends Hailey and Justin Bieber After Fans Chant 'Selena Gomez' at 2021 Met Gala Ireland said cousin Hailey Baldwin and her husband Justin Bieber are "one of the happiest and most in love couples I've ever gotten the chance to be around" By Hanna Flanagan Hanna Flanagan Style + Beauty Assistant, PEOPLE People Editorial Guidelines Published on September 15, 2021 03:03 PM Share Tweet Pin Email Photo: Getty Ireland Baldwin is defending cousin Hailey Baldwin and her famous husband, Justin Bieber. After a TikTok went viral of fans chanting "Selena Gomez" when the couple arrived at the Met Gala on Monday, the 25-year-old model (whose parents are Alec Baldwin and Kim Basinger) clapped back in the comment section. "Selena Gomez fans camped outside the met trying to ruin Justin and Hailey's red carpet moment," text over the TikTok says. While the caption reads: "DISGUSTING," with several hashtags. Many TikTok users slammed the people in the video, calling the situation "sad" and "disrespectful." "That's not nice. True fans know Selena would not like that," one person wrote. (Gomez and Bieber dated on and off from 2010-2018). Ireland added, "They're one of the happiest and most in love couples I've ever gotten the chance to be around. They don't care about them," with a laughing face emoji. The unfortunate interaction fell on Baldwin and Bieber's third wedding anniversary (coincidentally on the same day as the Met Gala). The model, 24, revealed the sweet detail in a behind-the-scenes style video uploaded to her YouTube video on Tuesday, which documents her fittings and glam process for the annual benefit. "This is probably the most last-minute I've ever fit my dress," Baldwin shared at the beginning of the clip. Luckily, the black Saint Laurent column dress fit like a glove at her first fitting in Brooklyn, NY. During the session, Baldwin and stylist Karla Welch went back and forth with accessories as they experimented with two very different vibes: Grace Kelly-inspired versus a more natural look reminiscent of Los Angeles style in the 1980s. Kevin Mazur/getty "I'm debating on the gloves because I'm trying to decide if the hair should be down or up. I've never worn my hair down at the Met," she explained. "It's always been up every single year. I like like it down with the dress. If I do it up, it would be like slick slick."

At the conclusion of the fitting, it's unclear which aesthetic Baldwin will choose, but she seems set on getting out of the car and walking the red carpet in her signature black sunglasses. During the clip, the star also shared, "Justin and I have never gone to the Met together, and it's on our anniversary."

In the end, Baldwin and her team went with the more "simple, all-American" option, sans gloves. She added a Tiffany & Co. diamond choker for a touch of glamour. "You just look cool," Atkin said of the effortless hairstyle and natural, glowy makeup. Bieber, meanwhile, donned a sleek black tuxedo by La Maison Drew (an extension of his Drew House label), painted sneakers and Jacquie Aiche jewelry. He walked the red carpet with a Drew House briefcase featuring the brand's signature smiley face logo. "I feel like the Met is alway just a very cool night to celebrate fashion," Baldwin told Keke Palmer on the red carpet. "We both love fashion, and we both love being able to celebrating designers." The Met Gala Will Return in September with a 2-Part Exhibition Focused on American Fashion When asked about his style evolution over the years, Bieber explained, "I think as I become more of an adult, things just [started] to evolve and change. I'm married now so I think things just become more...adult now." The theme of the 2021 Met Gala — which came after a canceled 2020 Met Gala and a postponed May date — was In America: A Lexicon of Fashion.
