*Maybe Rihanna isn’t as cool as she thought she was. The pop star may be canceling the some of her tour dates due to low sales. Her upcoming Loud tour with opener Cee Lo Green hasn’t quite caught on with enough people, according to the NY Post.

“It has been a big disappointment,” claims the Post’s source. “The ticket sales in big US cities like Boston are so bad, they will barely cover basics like the lighting and other arena costs. Tour managers are begging local radio stations to do giveaways.”

Just to put it all into perspective, a show scheduled for July 24 at the TD Garden in Boston requires at least 15,000 ticket sales just to break even only sold 3,700, resulting in a $500,000 loss.

Yikes!

The tour kicks off on June 4 in Baltimore and will continue in major cities across North America. There is no word, however, which dates will be canceled. (Boston sounds like a good bet.)
