You know how guys get the father’s permission to ask for a daughter’s hand in marriage? Well, do you ask permission to kiss someone’s girlfriend in a movie? You do if you’re Josh Duhamel and you’re in a movie with Ryan Seacrest’s real life love interest Julianne Hough.

“Yes, I did feel the need to seek approval from Ryan [Seacrest] before we started shooting the movie -- mostly out of respect for Ryan and the relationship,” Josh told Access Hollywood at the premiere for Safe Haven. “But it was rather awkward!”

The object of Ryan’s affection, Julianne, joked about her faux pas in forgetting to ask Fergie for the okay.

“Once [Josh] did it, I was like, ‘Oh shoot! Should I call Fergie? Whoops!’” the gorgeous star said with a laugh.

Ryan Seacrest and Julianne Hough are such a gorgeously sweet couple, we doubt Fergie had any jealous pangs. After hearing Ryan gush about Julianne on Chelsea Lately, calling her “the best part of every day,” we think everything will be just fine.

What do you think about Ryan and Julianne? Aren't they just one of Hollywood's most fabulous couples?
