Her mother, Amy Wagner, was diagnosed with stage 3C metastatic ovarian cancer in October 2012 and is currently on palliative care.
So, on May 10, the day before her mother's 56th birthday, Lauren surprised Mom at her Wheaton, Illinois, home with a flash mob of 50 of Wagner's closest friends and family members from five different states.
"I am not sure she will really understand how much that she has given to us," Keppel told NBC's Today show.
The video, which shows the group dancing to "The Best of My Love," also shows Wagner overwhelmed by the surprise.
"It is the most amazing thing that has ever happened to me," Wagner told the TV program. "I just love them all so much. I am really, really blessed."
