The Roush Fenway driver was on lap 319 of the race when he bumped Patrick’s No. 10 Chevy, sending her car into the back of defending Sprint Cup champion Brad Keselowski's vehicle. Both Patrick and Keselowski sustained significant damage and had to take their cars behind the wall for repairs.
While Keselowski later took the blame for the wreck, he elaborated after the race to reporters about how the accident happened in the first place.
"I was three-wide with Danica and didn't know it and I cut her off and wrecked her and myself," he said. "I feel bad for her and I send my apologies to her. It's just a long night for the Miller Lite Ford. We'll move on. That's all you can do."
As Patrick and Stenhouse Jr. have much been the topic of conversation in NASCAR news since the drivers announced in January they're dating, all eyes have been on the two to see how their relationship off the track would affect the one they have on it.
"I always say I'll race people how they race me until they do something to make me change my mind,” Patrick told reporters in an interview earlier this year. “I don't anticipate that changing at all, or us having any issues on the track."
Patrick later finished 29th overall while Stenhouse ended up getting entangled in a second wreck later and finishing 14th. Kevin Harvick and the No. 29 Budweiser Chevrolet went on to take the checkered flag at Charlotte.
