The original cast member of the Bravo hit reality show took to Twitter to reveal the reason why she ended up walking off set. "I got so upset and frustrated with the constant grilling I walked off the set," she tweeted.
"Then I unzipped my dress to remove my mic pack. Embarrassing moments. There are several tonight on #rhobhreunion."
However, Andy Cohen admits that he found the unzipping of the dress "iconic"
"I personally found the dress unzip to be iconic!," Andy tweeted.
To which Grammer replied: "Thank you @Andy," adding some smiley emoji faces.
