While most of us opt for trackies or leggings ahead of a long-haul flight, businesswoman Paris instead went for a slashed to the naval dipped hem dress teamed with killer high heels and, of course, her trademark sunnies.
Paris, 32, was joined by boyfriend River Viiperi as they browsed a book store before catching their flight to Barcelona.
While we all know Paris loves jet-setting around the world, this trip is particularly special as it's to River's hometown.
And in typical Paris-River style they weren't shy when it came to gushing about their smitten status on arrival. River tweeted: "Finally back in Spain! Love the fact that I'm here with my beautiful Blondie @ParisHilton #LoveHer ."
And Paris was quick to retweet a follower who said: "River is an amazing boyfriend. All he (does) is love her & treat her the way she deserves! @ParisHilton is his queen!"
Paris and River are in the Spanish city for Barcelona Fashion Week where model River will be strutting his stuff on the catwalk.
Paris tweeted from preparations at one of the designer houses: "At fittings with @RiverViiperi, he looks so hot in every outfit they have him try on. #SexyBF."
