Hollywood Dirt: Justin Bieber Accused of Battery by California Neighbor + Jay Z Gets Called Out by ‘Puppy Love’ Guy & More

CELEBRITY BEEF - JAY Z AND ... WAIT, WHAT?! PAUL ANKA?: Here's a sentence I'm willing to bet you never thought you'd hear: There's a possible beef brewing between between JAY-Z and Old School music legend PAUL ANKA (Google him, kids!).

Here's the backstory ... For reasons that weren't explained, the paparazzi caught up with Anka outside an L.A. restaurant, and conversation turned to talk about his upcoming "Duets" project. The guy asked Paul if he was going to do what all the cool kids like JUSTIN TIMBERLAKE are doing these days: a duet with a rapper.

Paul said no, but he did consider it. In fact, he wanted JAY-Z to be on the album -- but Jay wouldn't return his calls. Quote, "I called up Jay-Z, because he did a track [with] 'My Way', [so] I loaned him [that] track. I I called him up, but Jay-Z has totally blown me off. He won't answer my calls, he's inappropriate in his behavior."

Dang Hova! I luv ya but disrespecting the "Puppy Love" guy ain't cool!

CHRIS BROWN REVEALS LESSON LEARNED AFTER RIHANNA BEAT DOWN: In an interview with the Mantastic and recently available RYAN SEACREST, CHRIS BROWN says he learned an important lesson after he beat up RIHANNA four years ago.

"You can lose it all. I'm not just saying fame or stardom because that's not what it's about," he adds. "I'm talking about dignity [and] integrity. You know, you lose yourself in a way."

And even though he was just shy of his 20th birthday when that happened, Chris is not blaming his actions on his youth, admitting he was old enough to know better. He says he's worked hard over the years to earn back Rihanna's trust and prove, quote, "how remorseful and sorry I was," adding he's "eternally thankful and grateful" for her support.

'DANCING' SHOCKER: No one got kicked off "Dancing With the Stars" last night because DOROTHY HAMILL quit the show just after being pronounced "safe."

Hamill said her spinal surgeon told her it wasn't safe for her to keep dancing and that she felt it wouldn't be fair to stay when she couldn't "give it her all" and do the things she needed to do. Her decision means the Bottom Two, boxer VICTOR ORTIZ and 'Housewife' LISA VANDERPUMP, will live to dance another day.

BAD BOY BIEBER BEEFS WITH NEIGHBOR: JUSTIN BIEBER wasn’t back home for long from his publicity nightmare-filled European tour before getting into yet another headline-grabbing incident. TMZ reports Bieber is being investigated for battery after getting into a verbal altercation yesterday morning with one of his neighbors, which allegedly turned violent.

Word is the argument started because Justin was racing his new Ferarri around the block at an estimated speed of 100 miles per hour. The guy who called the cops admits he was "smoking hot" over the way Bieber endangered the kids, who are off this week on Spring Break. The guys claims Justin got physical and threatened him with harm ... but Justin's peeps say he walked onto Bieber territory and began screaming about loud parties that took place while he was on tour. The Los Angeles County Sheriff's Department is trying to unravel the tangled mess.

On another Bieber note … Will someone please tell Justin that he doesn't have to take his shirt off everywhere he goes? First he was photographed walking the streets of London shirtless, and now, for some inexplicable reason, he decided to walk through a freezing Polish airport sans shirt and looking like a fool with his pants on the ground.(PHOTO) (PHOTO)

A spokeswoman for Lodz Airport tells Reuters, "He wasn't told to take off his clothes. He had no metal objects on him. He's quite skinny, so I assume he was probably freezing." Dude! Seriously, you're not exactly Ryan Gosling or even Ryan Reynolds, OK? Keep your shirt on!

LOHAN LUNACY: One day after being a total pro and impressing everyone on the set of CHARLIE SHEEN’S new TV show “Anger Management” Linds good behavior has come to an end. Monday, Lindsay not only showed up 45 minutes early to film her guest spot, her first scene was spot-on. According to a TMZ source, "Lindsay knew her lines cold and her timing was perfect. She was really funny."

Yesterday was a whole different story though. LoHo was reportedly two-hours late, and, as one on-set insider put it, “looked and sounded terrible. It was like night and day.” Based on the rasp of her voice, sources guessed she’d stayed up all night smoking something. Supposedly. Allegedly.
