Bethenny Frankel has had a rough week.
"Bethenny was sobbing," a show insider tells RadarOnline.com of the tough-as-nails businesswoman, who filmed the show's special late last week. "She had a complete meltdown."
So, what— or who— broke the unbreakable Frankel? Sources say the 45-year-old single mom had an "epiphany" about her behavior over the past season after watching a montage of her nastiest spats.
"She was genuinely upset by how she came across onscreen," the insider explains. "Often, she doesn't realize how she comes across."
Also, according to the source, the star was exhausted from the 12-hour shoot with host Andy Cohen.
