He reportedly claimed they were driving in Florida when a photographer veered in front of them trying to take a picture, forcing the couple to swerve out of the way and hit a concrete barrier.
He swerved the auto to the left in an attempt to avoid a crash. Her boyfriend says that collision caused her to hit the windshield which led to her eventually ending up on the floor of the vehicle.
In a tweet, Samantha - who attracted headlines in the past when she announced she was planning a tell-all book called The Diary of Princess Pushy's Sister - claimed it was her idea for her father to be photographed in a series of royal wedding shoots, where he lives in Mexico.
The paparazzo fled the scene, and E.R. doctors are now treating Samantha. She's reportedly suffering from a possible broken ankle as a result.

Now it seems another member of the Markle family has been hospitalised.
Thomas Markle told TMZ that Meghan had contacted him on Tuesday - first by phone, and then by text, and expressed her love and support after he pulled out of her nuptials.
Samantha insisted that she was "entirely the culprit" behind her father's staged pap shots and said that it was not "money motivated" but in the hope his media image would improve. "I think a person has a right to say 'enough is enough, I wasn't to be shown how I really am". She's way out of her league to tell me that I can't speak.
"And how do you defend yourself when there's no evidence, there's nothing beyond the created social label that creates the public emotional swell and when it gets that big it's overwhelming", Samantha added. "You have been trashing her for two years, you little vulture!"
