Liar Liar, Paris’s pants are on fire, and not just from a scorching case of herpes.  After telling Larry King that she’d never even done drugs, Us Magazine is reporting that she openly smoked marijuana with Cisco Adler while out singing karaoke the other night.

The pair arrived at nearly 1 a.m. with two other girls. In skinny jeans, a black tank and a sequined top, Hilton didn’t get her own cocktail, but she stole sips from Adler’s vodka tonics throughout the night. Later, the burgeoning popstar sang "Bette Davis Eyes" in honor of a friend’s birthday, and stayed onstage for an unexpected encore when the DJ started playing her single, "The Stars are Blind." Musician Adler performed "Brown Eyed Girl," and then left the stage for Hilton’s side.

The duo, who Usmagazine.com sources witnessed making out more than once, were perhaps feeling loose and lovey due to the marijuana they were openly smoking at the club. As the 4 Non Blondes song "What’s Up" played in the background, Hilton sang along, replacing the chorus’ "what’s going on" lyric with "let’s smoke a bowl!"

I’m hoping for her sake that she had "bowl goggles," as Cisco looks like he could be the love child of Schneider from "One Day at a Time" and Carrot Top.

Rappers JaRule and Lil Wayne were charged Sunday night for criminal gun possession in separate incident, police said.

Lil Wayne, whose real name is Dwayne Carter; and Ja Rule whose real name is Jeff Atkins was in Manhattan—Carter performed at his concert at the Beacon Theatre shortly after being spotted smoking marijuana and carrying a 40-caliber pistol, authories said.

An hour earlier, Atkins was stopped for speeding and the police also found a 40-caliber pistol. It was unclear if Atkins performed at the theatre that night.

‘Uh-Oh’ is the name of the new song by the rappers.

What a perfect title song for the two and on the top of that get arrested on the same night.

It’s almost not even fun any more, this documenting of the amazing and inspiring transformation of Paris Hilton from cavorting as a typical Hollywood girl-gone-wild to making a difference as an altruistic, party-eschewing, drug-avoider. Yup. No fun.

Guess being the new-and-improved Paris isn’t fun for her either. Page Six has the cannabis dirt:

Although she told Larry King she’d never done drugs, the newly spiritual heirhead emerged from an SUV in front of Hollywood club Teddy’s the other night in what witnesses describe as a cloud of marijuana smoke. "She took a huge puff off of a joint, then opened the door and exhaled the pot smoke basically in my face," one clubgoer told us. At least she wasn’t driving. Hilton’s camp didn’t get back to us.

What a lady. And we thought the shots of Patron were something. Gone are the relatively peaceful Hawaii days, where she tried to keep her nightlife under cover.

Aloha.

Miss April 1989 was arrested over the weekend on an alleged DUI. Oberlin, Ohio police pulled over Jennifer Lyn Jackson and found beer bottles, marijuana, and rolling papers in her car. 

The former bunny managed to blow .077 on the breathalyzer, just sneaking under the state’s .08 limit. That’s like passing with a D minus grade. Not great, but passing nonetheless.

Jackson is pleading not guilty and will appear in court next week. You think Heff will still hire some good lawyers for her?

Al Gore III has been in trouble many times before. Is this a bad parenting issue?

- In 1996, he was suspended from his high school for smoking marijuana.
- In August 2000, he was ticketed for reckless driving by North Carolina police for driving 94 mph.
- In September 2002, military police arrested him on suspicion of drunk driving near a military base in Virginia.
- In 2003, he was charged with marijuana possession in Maryland after police stopped the car he was driving for not having its headlights on.
- In February 2004, he entered a substance abuse program as part of a plea agreement.

Al Gore’s son was pulled over for speeding on a California freeway early Wednesday and arrested on suspicion of possessing marijuana and prescription drugs, authorities said.

Al Gore III, 24, was driving a blue Toyota Prius about 100 mph south on the San Diego Freeway when he was pulled over by sheriff’s deputies who said they smelled marijuana, said Sheriff’s Department spokesman Jim Amormino.

The deputies searched the car and found less than an ounce of marijuana along with Xanax, Valium, Vicodin, and Adderall, which is used for attention deficit disorder, Amormino said.

"He does not have a prescription for any of those drugs," Amormino said.

Gore was being held in the men’s central jail in Santa Ana on $20,000 bail.
