Mariah Carey is not going to like this when she hears it. Apparently, the diva and former chart topper is having a hard time selling tickets to her Las Vegas show, making her Las Vegas residency one of the less desirable shows on the strip, compared to other megastars like Britney Spears and Jennifer Lopez.

Nick Cannon & Stevie J Nearly Brawl Over Mariah Carey? Details Here 

According to Naughty Gossip on Monday, while Britney and Jennifer's shows come with high-energy dance moves and non-stop action, the only thing Mariah has to offer is her voice--and unfortunately her fans are just not buying it.

In fact, things are so bad for Mariah that during a two-week stint, more than 4,000 of her tickets went unsold.

One source told the site, "Mariah is not aware of the problem. Her people are giving away tickets to try and make the house looks full. They are also moving everyone from the cheap seats downstairs to the parts of the theatre that she can see."

The insider added, "This cannot go on for much longer. Like Bette Midler they will cancel her show. That will kill her, especially with JLO selling out across the street."

So far, a rep for Mariah has not made any comments about the report.
