LOS ANGELES – A stakeout leads to a smooch on ABC’s crime drama “Castle,” with Rick Castle and Kate Beckett finally sharing their first kiss.

Played by series stars Nathan Fillion and Stana Katic, the pair locked lips in a scene filmed outside a downtown warehouse late Thursday for a January episode.

As “Castle” fans know, the show’s weekly whodunits share equal weight with the will-they-or-won’t-they romance conundrum for the lead characters.

The Castle character is a best-selling mystery writer and single dad who is a consultant to the New York Police Department. Beckett is the no-nonsense detective ordered to work with him. Their growing sexual tension — and banter — is reminiscent of the 1980s “Moonlighting” mystery series with Cybill Shepherd and Bruce Willis.

Sooner or later, however, TV viewers demand results from such chemistry lessons.

Andrew W. Marlowe, “Castle” executive producer-creator, said Friday he’s aware that many loyalists are rooting for Castle and Beckett to “take their relationship to the next level.” The show couldn’t hold off forever, Marlowe said.

But ratings can suffer when a lively mating dance turns to humdrum romance, so expect “Castle” to take it slow on the road to love.

The Castle-Beckett smooch comes during an episode about Beckett’s long-frustrated effort to solve her mother’s murder.

The episode’s January date has yet to be determined, ABC said.

‘Suge’ Knight taken in on traffic warrant

LOS ANGELES – Authorities say a rap mogul was arrested on an outstanding traffic warrant as he left a restaurant near Universal Studios outside Los Angeles.

Los Angeles County Sheriff’s Sgt. Shawn Ruda said Marion “Suge” Knight was freed about an hour after his arrest early Saturday.

Ruda told the Los Angeles Times that Knight was stopped by deputies, who ran his name through computers and found he was wanted on a minor traffic warrant.

Knight was brought to West Hollywood, cited and released.

No bail for ‘Pretty Wild’ star

LOS ANGELES – A reality TV star who pleaded no contest to burglarizing actor Orlando Bloom’s home is being held without bail in Los Angeles for allegedly violating probation.

A judge Friday issued the order for Alexis Neiers after the star of the E! reality series “Pretty Wild” was arrested on suspicion of possessing black tar heroin. A hearing was slated for Thursday.

Neiers, 19, pleaded no contest in May to a residential burglary charge stemming from a 2009 theft at Bloom’s home. She was sentenced to six months in jail and three years of probation.

Authorities said she was arrested Wednesday during a probation compliance check. The heroin and a fake driver’s license were found in her purse.

Neiers was one of six people arrested in the string of burglaries at celebrities’ homes.

Actor arraigned in murder

NEW YORK – An actor accused of hacking his mother to death with a sword was arraigned Friday from a hospital prison ward on charges of second-degree murder.

Michael Brea neither spoke nor entered a plea. He was also charged with criminal possession of a weapon after investigators found him in the bedroom of his apartment with a 3-foot sword. His 55-year-old mother, Yanick, was found in the bathroom Nov. 23.

The attorney who represented him at arraignment did not return a call seeking comment.

Brea, 31, had small roles in ABC’s now-canceled show “Ugly Betty” and the movie “Step Up 3D.”
