Gwyneth Paltrow insisted Friday on the witness stand that a 2016 ski collision at an upscale Utah ski resort wasn’t her fault, claiming it began when the man suing her ran into her from behind.

The actor-turned-lifestyle influencer testified that the crash shocked her — and the way the man’s skis veered between her two legs made her worry at first that she was being “violated,” she said.

After sitting in court for four days, Paltrow remained calm and collected for more than two hours on the witness stand. Members of the Park City jury sat transfixed while she categorically denied fault for the collision.

Terry Sanderson, the retired optometrist who is suing her, is expected to give an opposing account of the crash when he takes the stand first on Monday.

Throughout Paltrow’s heavily anticipated testimony, the founder-CEO of Goop calmly and repeatedly said that Sanderson, sitting several feet away in court, ran into her — causing the two skiers to end up splayed out on the beginner run with Paltrow on top and Sanderson beneath her. In the seconds after the collision, Paltrow acknowledged that she yelled at Sanderson and didn’t stop to ask if he was OK. Paltrow testified that she stood nearby on the mountain as one of her family’s four ski instructors promised to give Sanderson her contact information and file an incident report.

In an exchange that touched on recurring themes of the trial, Sanderson’s attorneys attempted to depict the decision as reflective of celebrity carelessness, while Paltrow insisted that she — not the 76-year-old man suing her — was the wounded party.

To draw the jury’s attention to Paltrow’s wealth, Sanderson’s lawyers probed Paltrow about the price of ski instructors at posh Deer Valley Resort and her decision to leave the mountain to get a massage the day of the crash.

Sanderson and his multiple-member legal team at one point dispersed themselves across the courtroom to possibly reenact the crash for the jury, whose members perked up after days of yawning through jargon-dense medical testimony about his broken ribs, concussion and brain damage.
