“Beverly Hills, 90210” bad girl Shannen Doherty has rolled the dice on marriage again — tying the knot for a second time.

Her new hubby, Rick Salomon, is an independent producer and a high-stakes gambler, sources say — and the two said “I do” in a quickie Las Vegas ceremony just weeks after they met.

“Shannen is in love and incredibly happy,” said her publicist Leslie Sloane.

“Her family, including her parents, and her best friends were at the wedding on January 27.

“Afterwards, they all went out for a nice dinner.”

The talented actress — who pleaded no contest to a drunk driving charge after she was arrested in December 2000 — had been dating her former “Charmed” castmate, Aussie hunk Julian McMahon. But she listened to her heart and dumped him for Salomon, who’s 33.

Shannen, 30, met Rick at the Standard Lounge in West Hollywood on the Sunset Strip, an in-crowd watering hole frequented by many actors and actresses, a source close to the newlyweds revealed.

“He’s a gambler who spends a lot of time in Las Vegas, betting big on football and basketball,” said the source.

“He invited Shannen to a Christmas bash he threw in the penthouse of the St. Regis Hotel in Century City — and they ended up spending the entire evening together.

“Within days Shannen had moved into Rick’s Hollywood Hills home.

Shannen wed actor Ashley Hamilton in September 1993. They divorced in April 1994.

“They were in Las Vegas the weekend before the Super Bowl — and suddenly decided to spin the wheel on matrimony in a little wedding chapel.”

Shockingly, Shannen and Julian shared a steamy vacation on the Caribbean island of St. Barts just last July.

And pals are flabbergasted by her quickie wedding to Salomon.

“After Shannen and Julian came back from St. Barts last summer, she seemed to be so in love,” said a source.

Besides her trouble over the drunk driving charge, Shannen walked away from her starring role on “Charmed” last May.

“Shannen has kicked off 2002 with a new outlook — and a new husband!” said the source.

“She’s gambling on love!”
