The Irish model, who finished fifth in last year's poll, slipped on some "super-skimpy lingerie" and tipped "gorgeous" models Daisy Lowe and Olivia Palermo to finish strongly on the 2013 list.
"The shoot was great! I loved wearing the super-skimpy lingerie. It's great doing a shoot when you feel so sexy," she gushed.
"I remember FHM 100 Sexiest Women in the World from when I was at school! All the boys would buy it and the girls loved looking through it."
Salpa also teamed up with models Rosie Jones and Franziska Klein to celebrate VO5 Extreme Styling's partnership with the FHM 100 Sexiest poll, surprising punters at a top London barbers with the ultimate hair treatment.
Although she may have finished behind Tulisa Contostavlos, Cheryl Cole, Rihanna and Jones in FHM's last survey, Salpa did collect the accolade of being 2012's highest new entry.
"People always talk about the 100 Sexiest - girls as well - and to think that you'd actually be in it," Salpa declared at the time.
