March 14 (Reuters) - Tilman Fertitta's Fertitta Entertainment is negotiating to buy Caesars Entertainment ( CZR ) for $32 per share, at an equity value of $6.5 billion, CNBC reported on Saturday, citing sources close to the situation. 

Fertitta's terms for Caesars include an enterprise value of $31.5 billion, given the gaming company's substantial debt, the report said.

Reuters could not immediately verify the report. Fertitta Entertainment and Caesars Entertainment ( CZR ) did not immediately respond to Reuters' requests for comment outside regular business hours.

Deal talks are taking place within a 45-day exclusive window, this weekend at Fertitta's headquarters in Houston, CNBC added.

The Wall Street Journal reported earlier this week that Fertitta Entertainment has been discussing paying around $34 a share for Caesars, giving it a value of roughly $7 billion.
