Bethenny Frankel’s had better weeks.

In the midst of a fierce, mudslinging fest with estranged husband Jason Hoppy over custody of their daughter, Bryn, the 43-year-old reality star got a reality check on her fading celebrity Thursday, as a book signing she headlined drew approximately FOUR fans, leaving event organizers to scamper for warm bodies to soothe her ego before she made an early exit.

The miscast talk show host showed up to the Javits Center in Manhattan for a 2 p.m. signing of her latest literary endeavor, a children’s book titled “Cookie Meets Peanut” — the problem was that no one else did!

“At 2:15 p.m., there were four people in line for Bethenny,” an insider told the NY Post. “Representatives for her publisher were sent out around the expo to recruit people to come to her stand. Through sheer hard work they managed to get some people over. After blaming others for the poor turnout, Bethenny left the show early.”

The paper’s source went on to say that while she was slated to remain at her booth until 3 p.m., she left at least 20 minutes early in light of the embarrassing turnout.
