Actor Danny DeVito and his wife, actress Rhea Perlman, are splitting after 30 years of marriage.

Even though he stands only 5 feet tall, DeVito, now 67, is quite the flirt when it comes to women, a source told Radar Online.

Apparently things haven’t been going well for the old “It’s Always Sunny In Philadelphia” and his wife for 10 years now.

“He may not appear to be a ladies’ man, but Danny certainly gets a lot of female attention,” an "insider" close to the family told Radar Online.

“Danny can be quite the flirt and because of his powerful status in Hollywood, he’s not ashamed to abuse his position and chat up young, aspiring women looking to make it in the industry.

“Despite his reputation as a lovable, funny guy in movies and on TV, Danny’s actually quite the flirt and ladies' man. Like a lot of red-blooded males, if he sees an attractive girl in a coffee shop or walking down the street, he will give her the eye.

“After years of turning a blind eye to it, Rhea finally snapped. She had enough of his bad-boy behavior and wanted an end to their marriage.

“The breakup has been on the cards for a long time, probably over 10 years, because they haven’t been happy for a long, long time,” the source said.

The two married in 1982 and have three children together: Lucy Chet, Grace Fan and Jacob Daniel.

The actors worked together on the classic show “Taxi” from 1978-1983 and also starred as husband and wife in 1996’s “Matilda.”

The production company they founded together in 1992 was responsible for popular films like “Pulp Fiction,” “Garden State,” “Erin Brockovich” and “Freedom Writers.”

TMZ later wrote that Rhea Perlman looked “cheery” after news of the split broke.
