The FBI’s dossier on Tinsel town’s top secret poker ring identifies Spider-Man star Tobey Maguire as the shadowy club’s “best player” and includes allegations some players often indulged in illicit drug use.

The sensational files on the sophisticated and organized illegal poker group were started after Los Angeles-based agents spoke to crooked hedge fund manager Bradley L. Ruderman.

As part of his confession to a $44 million Ponzi scheme, Star has learned Ruderman ratted out his one-time opponents and spilled the details of their clandestine games, which were held at the homes of players or in five-star hotels in Beverly Hills, such as The Four Seasons.

Hollywood poker madam Molly Bloom won't cooperate with MLB's investigation into the New York Yankee's Alex Rodriguez involvement in the high stakes poker games, RadarOnline.com is exclusively reporting.

Molly Bloom's lawyer Ronald Richards tells RadarOnline.com: "My client, Molly Bloom, won't be answering any questions," from Major League Baseball's Bud Selig about A-Rod's poker games.

Major League Baseball commissioner Bud Selig has ordered New York Yankees star Alex Rodriguez to appear before investigators over allegations -- first published in Star magazine -- that he played an illegal poker game where cocaine was openly used and another which turned violent.

"We take this very seriously and have been investigating this matter since the initial allegation," an MLB spokesperson told Star, in an exclusive statement.

"As part of the investigation, the Commissioner's Office will interview Mr. Rodriguez."

New York Yankees star Alex Rodriguez played in an underground, illegal poker game where cocaine was openly used, and even organized his own high-stakes game, which ended with thugs threatening players.

A blockbuster Star investigation, published on RadarOnline.com, has uncovered the sordid charges being made by eyewitnesses who played in games with A-Rod, in the top-secret Texas Hold ’Em circuit.

Molly Bloom, the woman at the center of the Hollywood poker scandal, has formally responded to a lawsuit filed against her and denies organizing the high stakes poker games that were held at luxury hotels, RadarOnline.com is exclusively reporting.

The lawsuit was filed against Bloom in the United States Bankruptcy Court for $473,2000 by Howard Ehrenberg, a court appointed trustee who is attempting to recoup money from jilted investors in a Ponzi scheme orchestrated by Brad Ruderman.

Tobey Maguire was such a poker playing fiend that the Spider-Man star had separate bank accounts devoted entirely to his favorite card game.

RadarOnline.com has obtained a legal response that Maguire filed on July 5, 2011, to a lawsuit that was filed against him for money he’d won from convicted Ponzi schemer Brad Ruderman, and included copies of checks to prove he both won and lost money during the illegal poker ring games, putting him about even with Ruderman.

Not only does Maguire, 36, label his two checking accounts as “Poker Account” and “Poker Account (2)”, but the actors checks included as evidence in his legal response give an eye-opening look at just how often he was playing poker and dishing out money for his hobby.

In a new expose, Star has ripped the lid off Ben Affleck's secret gambling life and uncovered shocking charges that the actor had an almost half-million dollar poker debt to one of the most powerful movie moguls in Hollywood.

The sensational new accusations come after Star reported exclusively that the Academy Award winner was involved in a Tinseltown's top secret poker
ring involving A-Lister's Tobey Maguire, Leonardo DiCaprio and Matt Damon.

It's emerged Affleck, 35, even hosted his own game -- which was referred to in poker circles as "Ben's Game" -- at the Grand Havana Room in Beverly Hills, a high-end cigar club, around the time he was engaged to Jennifer Lopez.

Spider-Man star, Tobey Maguire has filed a response to the lawsuit he was slapped with in connection to a number of high roller poker games that Maguire and several other A-listers participated in.

In his response Maguire admits that he played in several games but denies they were ‘controlled’ or that they were illegal. Maguire insists that the games he participated in were not organized by poker games ringleader, Molly Bloom, despite her sworn affidavit to the contrary. Maguire requests that the lawsuit against him, seeking payment of over $300k related to winnings Maguire was paid by jailed hedge fund manager Brad Ruderman, be dismissed and seeks that his legal fees relating to the lawsuit be covered by the plaintiff.

The sister of a U.S. Olympian and former pro footballer has been revealed as the woman behind the mega-million underground Hollywood poker scene involving A-List actors, as first revealed in a Star magazine world exclusive investigation.

Molly Bloom, the sibling of two-time Olympic skier and Philadelphia Eagles player Jeremy Bloom, has been unmasked as the sexy go-to girl for high rollers who gambled millions of dollars in clandestine games at luxury venues such as the Beverly Hills Hotel, the Four Seasons and the Viper Room on Sunset Boulevard.
