Olivia Culpo dressed to the nines in a skin tight emerald green gown for the 2015 Miss Universe Pageant.
The 23-year-old wowed in her jewel toned dress at the event held at the Planet Hollywood Resort & Casino in Las Vegas.
The star, who was crowned Miss Universe in 2012, wore the floor-length fitted Thierry Mugler dress on Sunday.
The actress, who was named a judge for this year's pageant, dazzled in the long-sleeved frock, showing off her svelte figure.
The high-neck gown featured cut-outs near her shoulders and in the center, showing a hint of cleavage.
Olivia added a metallic clutch, dangling diamond earrings and a ring for a shimmery touch to the dark hued look
