Her long blonde locks were curled and cascaded around her shoulder, while her usual orange fake tan was toned down to a radiant glow.
The Big Brother winner also had demure fluttery false lashes, along with a natural pink lip.
Fans were quick to compliment the star on her elegant transformation.

Another commented: "Wow you look so much better without all that tan. Absolutely stunning!".
A third said: "You look beautiful , keeping this natural look I hope!".
However, in Isabelle's following snap, her thick eyebrows and dark fake tan were back.
One user commented: "Sweetie, not a good look!".
While another told her: "I usually dont comment stuff like this, and i dont care what people do, but you should really lay down the make up a bit...
"You look good, but you’d look even better with a little bit less. No hate or whatsoever".
