Paris Hilton’s boyfriend, 21-year-old model River Viiperi, was hospitalized over the weekend after a nasty skiing accident! Thankfully, it looks like River will be okay, but Paris says it was a “scary day” on the slopes.

Paris was celebrating her 31st birthday with boyfriend River on a ski trip to Lake Tahoe, California,according to Bang Showbiz. While they were enjoying some time on the slopes, River reportedly had a nasty wipeout and slashed open his leg.

"Such a scary day on the slopes today,” Paris Hilton posted on her Twitter account. “After seeing the gash on @RiverViiperi's leg, I almost passed out. I have never seen a cut that deep in my life. He is so brave, I can't even imagine the pain he went through today. (sic)"

Paris, who never left River’s side, said he “was doing a high jump while skiing & the ski sliced in to his leg! 19 stitches! Oww! (sic)"

After being released from the hospital, River posted his own Twitter update, thanking Paris for taking care of him. "Thank you for being there for me my Love, your the best Girlfriend in the world!! I'm so lucky to have you! #love (sic)"

Paris and River flew home to Los Angeles after the accident and decided to keep the rest of her birthday low key. "Can't wait to get home to play with my puppies & watch movies in bed with @RiverViiperi. Chill birthday night," Paris said.
