Philipps, 37, said she tried to call an Uber ride with her husband and when she got into the car, things took a weird turn, reported E! Online.
The actress described the incident on Instagram in a series of almost 50 videos.
Phillips said that they called a single Uber, not a shared ride. She said a driver in an SUV pulled up farther away from them and they got inside. She said she immediately felt uncomfortable.
"I started screaming, 'I'm not going to be killed today! I will not be killed today!'...'No! You cannot kill us! No!"
The actress said the two then jumped out of the car.
