The 16-year-old daughter of a top Lowe’s executive was killed and her two friends were injured after she crashed her Porsche into a tree near her family’s $2.6 million North Carolina mansion, cops said.

Stella Grace Bright was allegedly speeding when her two-seater 2014 Porsche 911 supercar flew off the road in Mooresville, near Lake Norman, at 3.20 a.m. Saturday — striking the tree and a rock landscaping wall, the Charlotte Observer reported.

Bright was pronounced dead at the scene, while her two friends were rushed to a hospital with unknown injuries, police said.

One of Bright’s friends had been sitting in the back section of the sports car, which isn’t equipped for passengers and has no seat belts, cops added.

Both Bright and her front seat passenger were wearing seat belts at the time.

Investigators haven’t yet disclosed how fast they believe Bright was driving at the time, but said speed was a factor.

The fatal wreck happened less than two miles from the Bright family’s $2.6 million lake house, The Daily Mail reported.

It wasn’t immediately clear if the Porsche — which retails anywhere from $60,000 to $120,000 and can reach speeds approaching 200 miles per hour — was owned by the teen, or if it belonged to her parents, Teresa and Chris Bright.

The teen’s father is the Vice President of Market Delivery & Final Mile at Lowe’s, according to his LinkedIn.

Bright’s twin sister, Olivia, was among those to pay tribute in the wake of her shock death, posting on social media that the teen was her “other half.”

“I don’t know how I’m going to live another day without you u meant the world to me and still do. You didn’t deserve to go this soon you really didn’t,’ Olivia wrote.

“I won’t stop thinking about you and I know you want me to be happy so I’m going to try to be happy just for you.”

Meanwhile, friends described the teen as a “beautiful soul” and someone who would always “make people smile in an awkward situation.”

“There are absolutely no words to describe how much you were loved and how we are all going to miss you so so so much,” friend, Nikki Degroot, posted on Instagram.

“I can’t even begin to describe with words how grateful I am to have met you and to be apart of your life. You are so amazing and caring ad [sic] kind and talented and you had such a beautiful soul,” another friend, Jocelyn Carroll, added.

“You always know how to put a smile on anyone’s face… you were the bestest sister I never got to have and I miss you so much. I’m so sorry I never got to say goodbye.”
