Salpa began modelling before leaving secondary-school, and has undertaken modelling assignments for various publications. She has made TV appearances on such programmes as The Podge and Rodge Show, Republic of Telly (as herself), Celebrity Salon, and Catwalk to Kilimanjaro. In August 2009 after posing in a bikini for a controversial photoshoot for Food & Wine magazine, the magazine apologised after complaints on Liveline.
Salpa later moved to the United Kingdom, and participated in the Channel 5 (UK) show Celebrity Big Brother where she was the third housemate evicted. In 2012 Salpa was listed 5th in FHM's "100 sexiest women" poll, and has since been increasingly featured in the magazine, before becoming the "cover girl" for FHM's 2013 "100 sexiest women" publication.
