In an interview with The Cut the professional dancer, model, actress and beauty blogger talks working for Bey, rehearsals, touring and make up.
"She hired me and then kept on hiring me. I booked with my first gig with Beyoncé in 2009 when she did "Single Ladies" in concert," she said.
"Then I went on to do the Billboard Awards and Oprah with her. And from then on, the Super Bowl and two weeks later, we were in rehearsals for the Mrs. Carter show."
Check out how Miss Ksyn and her ladies twerk it onstage.
When it comes to looking flawless onstage Tanesha says:
"Everyone (except Beyoncé) does their own make up. My beauty routine takes me about 45 minutes to an hour. Everybody else can probably do it in half of that."
As for her beauty esentials? "For performances, I use Oil of Olay products because they are really good for the skin.
"I start out with the basic face wash and use a toner after that. I use a Mac eye cream and a nice moisturising lotion, Olay Regenerist Micro-Sculpting Cream or Peter Thomas Roth's Oilless Oil. To make my makeup last, I always start out with a Bare Minerals matte primer."
Take a look at these photos from Tanesha's Instagram page of her working it during the On the Run tour. Proof that her beauty regime has serious holding power.
LOVE BEYONCE? She's the ultimate independent woman and her wardrobe ensembles are just amazing.
