Paris Hilton's Wardrobe Malfunction

March 25 -- Paris Hilton can blame her recent run-in with a horse on a wardrobe malfunction.

Instead of wearing, let's say, cowboy boots — or even sneakers — Hilton, 22, opted for stiletto heels when she went for a ride on a 7-year-old horse during a taping for The Simple Life 2 at the Bull-It Rodeo in Hernando County, Florida, on March 19.

Immediately after saddling up, the hotel heiress was thrown to the ground.

"Paris was wearing these big heels and kicked the horse right into the ribs," eyewitness Rex Hinkle tells Us Weekly's Hot Stuff.

"If you kicked me in the ribs, I would have done the same."

A Dazed Hilton Seeks Hotel Comfort

After the fall, Hilton appeared dazed and confused and there was blood on her face. She was airlifted to St. Joseph's Hospital in nearby Tampa where she was released after a few hours.

When she woke up the next day in her Hernando County hotel room (yes, it was a Hilton hotel), she complained that she was too sore to join Nicole Richie for their required day of working on a local resident's home-improvement project.

So what's a bruised heiress to do? Sources tell Hot Stuff that Hilton spent the day at a beach. And this isn't the only thing we've learned.
