River Viiperi Works The Runway At Barcelona Fashion Week

River Viiperi strutted down the catwalk at the Mango show at Barcelona Fashion Week on Monday, and of course, Paris Hilton was there to support her handsome beau!

Paris tweeted, "Just watched my love @RiverViiperi walk the runway for @Mango. Looking so handsome in @HeByMango's latest collection. #SexyBF," and she later added the photo collage of the two below and wrote, "Backstage at the @BrainAndBeast runway show with riverviiperi. #BarcelonaFashionWeek." Such a cute couple!
