Bootylicious Beyoncé Knowles got smacked with a $1.5 million lawsuit by a man who claims she breached a contract and didn't pay him enough for brokering the launch of the House of Dereon, her clothing line.

Meanwhile, big-time movie producer and George Bush 41 pal Jerry Weintraub - of George Clooney's three "Ocean's" movies and the "Karate Kid" flicks - snap-kicked the Starwood Hotel chain for unspecified medical damages and lost wages, claiming an out-of-control golf cart rammed into him last summer at the swanky Hotel Pitrizza on the Italian isle of Sardinia.

First Beyoncé. Manhattan businessman Greg Walker claims he introduced Jay-Z's girlfriend and her mom, Tina Knowles, to the folks over at Wear Me Apparel, Inc. (also defendants in his lawsuit), and that Beyoncé ponied up a pitiable $25,000 while Wear Me paid him only $85,000.

While that might sound like a nice chunk of change, Walker maintains Beyoncé received "approximately $15 million" in the licensing deal - and his contract calls for him to get a whole lot more.

Beyoncé's apparently vacationing spokeswoman didn't respond to detailed phone and E-mail messages.

As for the 68-year-old Weintraub, a pal of the Bush family from Kennebunkport, Maine, he claims he was "walking the grounds" of the hotel when he "was suddenly and unexpectedly hit by a golf cart, which was carrying luggage ... moving at a rapid speed ... thereby directly and proximately causing ... serious injuries to his body, and shock and injury to his nervous system and person, and great physical and mental pain and suffering."

Asked for comment, Starwood didn't respond by deadline
