"Teen Mom OG" star Mackenzie McKee is showing the aftermath of an intense cardio session that went down after the MTV reality star says she heard her late mother giving her the inspiration to get out and celebrate life. 26-year-old McKee took to Instagram over the weekend and shared with her 1 million followers what inspired her to hit the streets that morning for a run.
"Woke up at 7 and heard my moms voice loud and clear say 'get up and run for me," McKee wrote to fans.
