Charles Grusczynski reached a plea deal with prosecutors for selling fake tickets to at least five people via Craigslist.
Bieber visited Houston last month.
Prosecutors say Grusczynski's targets made the crime that much worse.
"They save their money -- their babysitting money, cutting-the-grass money -- to be able to afford tickets that are extremely expensive, and they look forward to these events for months, and to have their dreams, like the judge said, demolished and shattered by somebody who's just a career criminal," said Rob Fryer, an assistant district attorney in Montgomery County.
Grusczynski may have pulled the same scam in Dallas. He has similar convictions in Florida.
