Courtney, 19, went for a drastic image overhaul after her time on CBB last year, switching her light hair for a dark brown colour.
But, after a brief dalliance with the dark side, she's back to her golden best!
Courtney shared an image of her new locks via Twitter on 23 February, adding the caption: "Hair is amazing thanks to my beautiful hairstylist Anush Jambazian."
She'd previously said: "Feels so good to be back blonde."
Her hair definitely looks very Hollywood glam in the selfie, tumbling down her back in waves… but we reckon many viewers of the pic will be somewhat distracted by her teeny tiny dress.
One follower even replied: "Plz keep posting these kind of "Hair" pics! They are GREAT!! - #HA! (sic)."
Courtney found fame in the UK last August when she entered the Celebrity Big Brother house alongside stars including TOWIE's Mario Falcone, Geordie Shore star Charlotte Crosby and Saved By The Ball icon Dustin Diamond.
She was supported during her time in the house by then-husband Doug Hutchison, who was in the UK throughout her time there and turned up to every eviction night where she was nominated.
However, after returning to LA, Courtney and Doug announced their separation, saying it was a "mutual and amicable" decision and they will remain friends.
Courtney was 16 when she married Doug, who was 51. They'd met via an online acting workshop he was running.
