Golden Nugget Casino and Houston Rockets owner Tilman Fertitta isn't taking no for an answer and instead is preparing to make a second run at a merger with Caesars Entertainment (CZR) - Get Report , according to a report in the New York Post. 

Caesars rejected Fertitta's merger offer in November, but this time he could get help from activist investor and Caesars' controlling shareholder, Carl Icahn. 

Icahn has added to his stake in Caesars, the country's largest casino chain, for months and he currently owns a 28.5% stake in the company, including swaps, according to the Post's sources. 

Icahn is also in position to control half of the company's eight board seats. 

The Post reported that Icahn believes that the casino needs to trim its expenses, including the reported $330 million a year it spends on corporate expenses. 

Fertitta isn't the only one interested in a merger with Caesars. Earlier this week Reuters reported that the company was in the early stages of exploring a merger with Eldorado Resorts (ERI) - Get Report .

Caesars has provided some limited confidential financial information to the company as part of the negotiations, according to the report.

Shares of Caesars rose 1.9% to $8.53 on Thursday.
