Former Miss Universe Olivia Culpo publicly declared her love for boyfriend Nick Jonas by telling supporters that the pop star is "the person who puts a smile on my face every day" at her last official event.

Culpo was in Russia to pass on the beauty pageant crown to Venezuelan beauty Gabriela Isler on Saturday night (09Nov13), and in her exit speech onstage at Moscow's Crocus City Hall, the pretty American took a moment to thank her friends, family - and her boyfriend.

She said, "To the very special person who puts a smile on my face every day, I can't wait to start this new chapter with you."

Culpo also posted a photo of the couple embracing backstage just before the Miss Universe pageant on - a shot Jonas also uploaded, writing, "I got my eyes on you. You're everything that I see. Happy to be in Moscow supporting my girl on her final walk as miss Universe. So proud of you @oliviaculpo."
