Surprise! 'Big Brother 26' Star Ainsley Is Actually This Popular TikTok Creator

Season 26 of Big Brother is finally here, and we hope you're ready for a summer of mind-blowing twists and expecting the unexpected! For the first time in the show's history, the cast holds the power to vote in a 17th houseguest by majority rule.

In Part 1 of the Season 26 premiere, the first eight houseguests meet Ainsley, a spirited blue-haired surfer girl who eagerly introduces herself to the group and expresses her desire to compete alongside them. However, a twist unfolds when it's revealed that she is the BBAI . Now, the question remains: Who is her human counterpart? Here's the scoop!

Who is Ainsley from 'Big Brother 26'?

During the Season 26 premiere of Big Brother, diehard fans swiftly turned to social media to uncover Ainsley's true identity. Soon enough, viewers discovered that Ainsley is actually Cosette Rinab, a well-known TikTok creator.

With 2.2 million followers on TikTok ( @cosette ), Cosette provides her fans with a plethora of lifestyle content. Her most recent video, posted on Monday, July 15, sees her skillfully applying floral window film to her home's windows.

According to her official website , Cosette entered the TikTok scene in 2018 and has since teamed up with various brands for "consulting services and partnerships." She's worked with the likes of Dolce & Gabbana, Levi's, Puma, Tory Burch, and Boohoo, among others.

'Big Brother' fans felt the AI twist was too obvious.

While viewers accept Cosette being part of Big Brother 26, they're not too thrilled about how blatantly obvious the "BBAI" twist was.

"Ainsley's name literally starts with 'AI' like c'mon now LOL #bb26," one fan wrote on X.

A second user agreed, stating , "Ainsley?? The possible 17th houseguest, her clothes are giving Zenon and her name starts with AI."

"What in the zeetus lupeetuz... Ainsley definitely gonna be controlled by AI," a third Big Brother fan added .

Another viewer chimed in , "This girl is not playing for the money she's clearly the AI twist no? I don’t get it Julie make it make sense."

Many were horrified by the AI robot, describing it as something straight out of nightmares.

"That AI baby blue robot thing is what nightmares are made of," someone posted on X.

A second Big Brother fan commented , "Why is the AI so scary help? Can we vote her off?" while someone else said , "This was lame. Bring back Ainsley. This AI is creepy."

Yeah, the BBAI is definitely giving us the creeps — but sadly, we're going to have to deal with this blue entity the entire season. So, buckle up for what is surely going to be a wild ride full of twists and turns that no one will see coming.
