AceShowbiz - When Selma Blair chopped off her platinum blonde hair and debuted a fresh hairstyle, little did she expect to be mistaken for an iconic pop star. But what transpired at the airport left the actress and her fans in fits of laughter.

On Friday, November 29, the 52-year-old actress took to Instagram to share a hilarious video, recounting the moment an airport security guard mistook her for Australian singer Sia Furler. With her signature bright smile, Blair started the video saying, "Guess what?" and then panned the camera to the guard, who reenacted their interaction.

"Oh my god, you look just like Sia! Your hair," exclaimed the guard. Selma, playing along, responded, "I was with Sia last night for Thanksgiving. We all love Sia." To wrap up the amusing video, she blew an air kiss to the camera and wrote, "I love my friend, Sia," tagging the singer in her caption as well.

The songwriter, whose full name is Sia Kate Isobelle Furler, is renowned for her extravagant wigs that often leave her face obscured. She catapulted to worldwide fame with her 2014 hit "Chandelier." When she's not dazzling audiences with her unique wigs, Sia's natural look also showcases a platinum blonde hairstyle with wispy bangs, remarkably similar to Blair's new 'do.

This lighthearted episode comes on the heels of some positive health news from Blair. The "Cruel Intentions" star is still in remission for multiple sclerosis (MS), a condition she was diagnosed with in 2018. Speaking to Variety, she shared that her health has significantly improved following a bone marrow treatment and changes in her medications.

"I started feeling really better this last year, and I'm back at work and doing things so I will have things to announce," Blair revealed. She reflected on her pre-remission days, saying, "I had felt so weak and all the fogs and the movement really made it impossible to go out at night. I just had no strength. I didn't think I'd get to feel this grounded."

Selma Blair's candidness about her health and her sense of humor continue to inspire and entertain her fans. And while she may have momentarily been mistaken for another star, her unique light shines unmistakably bright.
