Alan Finkelstein and Marg Helgenberger are dating.
"MARG HELGENBERGER might want to investigate her new BF - The ENQUIRER has discovered he's been busted for allegedly dealing drugs and accused of domestic violence!
Marg, 51, star of CSI:Crime Scene Investigation is falling hard for Alan ...Finkelstein, who was charged with smuggling marijuana and accused of domestic abuse by his former girlfriend, a top model.
"Marg better be extra careful with this guy," a pal of Finkelstein's told The Enquirer.
"He's got a reputation fro being on the wrong side of the law.
Finkelstein, now 60, was arrested in April 1979 on charges of conspiring to import large quantities of marijuana from Thailand.
Witnesses testified Finkelstein once received more than $2 million worth of Thai sticks - marijuana wrapped around bamboo sticks - flown into New York's JFK Airport.
Facing 10 years behind bars, Finkelstein denied the charges and was found not guilty after a 13-week trial.
His then-girlfriend, model Esme Marshall, often accompanied him to court, sources say.
"Whether she came to court because she truly wanted to stand by her man, or Alan twisted her arm into doing so, I don't know," said the source.
Esme lived with Finkelstein for several years, and later claimed that he abused her.
"He used to not let me go to bookings," she said in one interview. "It was very weird. He tried to run me over once. He was jealous of my booker 'controlling' me."
Helgenberger has known Finkelstein for several years,and they started dating after her 19-year marriage to actor Alan Rosenberg officially ended earlier this year."
