Olivia Culpo and boyfriend Nick Jonas were talking mushy-mushy about nothing much Saturday around the 2013 Miss Universe competition in Moscow, where Culpo turned over her crown to winner Gabriela Isler, Miss Venezuela.

Culpo and Jonas, whose relationship went public in early August, were full of comments directed toward each other on social media.

"'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," Jonas posted on Instagram on Friday, with a picture of himself gazing upon a larger-than-life poster of Culpo.

Saturday he followed up on Twitter with, "Amazing time at miss universe 2013 congrats @oliviaculpo you were amazing. Now time to celebrate!"

Before the show started, Culpo shared an Instagram photo of the two of them with arms around each other backstage, nose to nose, captioning it, ""To the person who puts a smile on my face every day"....1 hour until show time :) #missuniverse"

She also included Jonas in backstage shot celebrating Reese's Peanut Butter Cups after the swimsuit portion of the show.

All of that, of course, being perfectly sweet.
