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.
