A source tells The Insider that after his show Saturday night, Bobby went back to his hotel and had a major breakdown. He didn't come back to L.A. Saturday because the people with him did not believe he was fit to travel. They said he was so distraught, a friend stayed with him inside his room last night to make sure he was okay and they kept someone outside the room as well in case further help was needed. The source notes that Bobby lost his mother last January and this has taken a severe toll on him.

According to the source, Saturday night was very bad and emotional, and they think Bobby is numb at this point.
