The fashion blogger is currently in South Africa with friends, and made sure she looked eyepoppingly chic for her 25th birthday - naturally!
Rosie showed off her trim figure in a white bow top from Bambah Boutique, which she teamed with a cutaway skirt from River Island.
While the skirt was high street - yah! - her shoes were not... Oh so Valentino! No wonder we like them so much!
With her hair loose and styled naturally, Rosie got the mix of holiday vibe and glamour SO right!
Rosie spent her birthday with twin sister Lily and their friends at swish Camps Bay - think Chelsea, but in Cape Town!
After enjoying a birthday breakfast fit for a princess, Rosie then got down to some serious sunbathing.
Sharing a sun-soaked snap in a cute bikini top, Rosie told fans: "Birthday selfie wearing @heidikleinswim bikini, @stellamccartney sunnies and @joubijewellery body chain."
Last time we saw Rosie on E4's Made In Chelsea she was being a supportive friend to Louise Thompson.
She also buried the hatchet with Andy Jordan in the butchers of all places as they brought their festive turkeys.
While we're not convinced she's forgiven Andy for meddling in ex-Louise's relationship with Alik, Rosie agreed to let bygones be bygones because she "didn't want bad vibes on her turkey".
We can't wait until the series returns later this year!
