New York- Supermodel Maggie Rizer is supermad.

The blond beauty is suing her stepfather and others she claims turned a blind eye while he drunkenly gambled away her $7 million fortune – a lot of it playing Quick Draw, the state video lottery game.

Rizer is taking aim at some of the most high-profile citizens of her hometown, Watertown, N.Y. – including the former mayor, a tavern owner whose Quick Draw machine swallowed much of her money, a suit filed in Manhattan Supreme Court charges.

“I think it’s ridiculous that grown men in upstate New York tried to hide behind my stepfather and make a fool of me,” Rizer told the Daily News yesterday. “I am not going to stand by and let anyone do that to me and my family.”

Rizer, 27, was a small town kid just out of high school when her career took off after her mother, Maureen, sent some Polaroids to a modeling agency.

Before long, the 5-foot-10 stunner was established as an international supermodel and commanding $30,000 a day. With no experience in finance, Rizer turned to stepdad, John Breen, an insurance agent, giving him power of attorney over her mounting fortune.

Between 1999 and 2002, Breen went on a bender, boozing and pouring countless dollars into Quick Draw electronic gambling machines in two local taverns – including one owned by former Mayor Jeffrey Graham, the lawsuit charges.

“The behavior of these people was horrific,” said Rizer’s lawyer, Edward Hayes. “It’s really, really awful conduct.”

Breen admitted stealing about $7 million when he pleaded guilty to grand larceny in March. He was sentenced to four years in prison.

Hayes said the suit seeks the return of $3 million Breen stole, though that figure may go higher depending on what can be established in court.

The suit accuses Graham, a longtime Breen friend, of plying him with free drinks, and accepting checks written on Rizer’s account to cover Breen’s losses, and allowing him to run a tab, in violation of state lottery rules.

Bar owners make a 6% commission on Quick Draw plays. Graham’s Quick Draw revenues rose from $732,464 in 1998 to $1,640,065 in 2001, according to court papers.

“It would be kind of stupid to comment on something I know nothing about,” Graham told The News yesterday.

The suit also accuses local bankers of doing nothing while Breen was draining Rizer’s account, even though he often was reportedly drunk while making withdrawals.

Only in late 2002 did bank officials question him about unusual activity on the account, the court papers say.

New York Post-SUPERMODEL Maggie Rizer has fashioned a $24 million lawsuit against her gambling- and alcohol-addicted stepdad – as well as those she claims enabled him to fritter away her hard-earned fortune.

The fresh-faced Rizer’s woes began when she gave her stepfather John Breen power of attorney over her bank accounts in her hometown of Watertown, N.Y.

Little did she know “Breen was spiraling downward as an alcohol abuser and gambler who stooped to stealing from his own family to cover his losses,” Rizer’s lawyer Ed Hayes wrote in the lawsuit filed yesterday in Manhattan.

The complaint estimates that between 1999 and 2002 the now-jailed Breen wrote a whopping 250 fraudulent checks to himself or to “cash” on Rizer’s fiduciary account at HSBC bank – siphoning off at least $3.5 million for his booze-fueled gambling binges.

Breen pleaded guilty to grand larceny, fraud and forgery charges on Oct. 22, 2004, and is currently serving 16 months behind bars.

But Breen didn’t act alone, the lawsuit states.

He was enabled by “the colossal failure of [Rizer’s] bank and other financial institutions . . . and by the greed of tavern owners who plied Breen with free drinks [and] encouraged him to gamble away huge sums,” according to court papers.

On top of seeking $13 million in damages from Breen, the suit goes after the owners of two local drinking holes – including former Watertown Mayor Jeffrey Graham, Breen’s pal of 20 years who owned a bar called Speak Easy.

Graham also allegedly accepted a $10,000 check from Breen that had Rizer’s name on it as a loan to open a second Watertown bar, the Paddock Club. Graham had no comment.

A second tavern owner, Todd Lavere of Kegler’s Lounge, is accused of willingly taking suspicious checks from Breen to pay off his $90,000 gambling debt.

Also named in the suit is HSBC and several other financial institutions, including Solomon Smith Barney – where Breen allegedly forged Rizer’s signature to withdraw money from her brokerage account.

“She was a very obviously successful model. They had to have seen that the money was hers. They knew the guy was broke,” Hayes told The Post’s Kati Cornell Smith. “Whenever Breen went to HSBC he was drunk. He’d go in at the end of the day, do his banking and then go back to his office and sleep.”
