On September 2, 2025, the streaming phenomenon Mafiathon 3—a marathon subathon hosted by Twitch’s most-subscribed streamer Kai Cenat—welcomed a surprise guest: pop icon Mariah Carey. The unexpected cameo turned the already electric livestream into an instant headline moment across social media and beyond.

As Carey entered the frame, Cenat greeted her with obvious delight. He unveiled a giant poster of her upcoming album Here For It All, scheduled to drop on September 26. Carey, stepping in to promote the project, helped pull away a drape to reveal the monochrome cover art in full. “Here For It All,” he announced, as fans across the chat erupted.

The moment didn’t stop there. Carey delivered an a cappella rendition of her classic hit “Heartbreaker,” her voice cutting through the virtual airwaves with timeless flair. She also talked about her nerves ahead of the album launch. “It’s always nerve-wracking when something so personal goes out into the world,” she shared, prompting both chuckles and nods from the audience.

Following the album reveal, the pair launched into a playful spelling-bee segment with Cenat’s crew. It was spirited and surprisingly competitive. Carey also took a quieter, heartfelt moment to address the audience: “Hold on to hope no matter what’s going on in your life. Pray when you need to pray, and don’t ever let anybody put you down.” Her message earned a round of applause from everyone present, streamers and fans alike.

Mariah Carey Name Drops

During their chat, Carey surprised many by naming contemporary artist SZA as one of her current favorites. The cross-generational nod sparked a wave of excitement among viewers who praised the icon for embracing newer voices.

Mafiathon 3 kicked off on September 1, 2025, with energy and star-studded appearances. Guests have included Kim Kardashian, Roman Atwood, Ray J, and Miles Caton. Each brought unique moments—from Kim’s table-tossing prank to Ray J’s chaotic exit—and all built toward Cenat’s ambitious goal: hitting one million subscribers by month’s end. Carey’s surprise visit fits as both promotional and emotional fuel for that mission.
