Earlier this week, it appeared that Britney Spears was close to signing a massive deal with Ceaser's Palace.  But, since that story broke, other properties in Las Vegas have thrown their hats in the ring.

According to TMZ, at least two other properties in Las Vegas has thrown their hats into the ring.  The competition could drive up the price for Spears.  Some have reported that Spears already signed a 2-year deal worth over $200 million, but TMZ claims those are false.

Celine Dion once signed a deal, worth about $100 million a year, to play in Vegas.  Dion's Vegas residencies have been some of the best selling concerts in history.
