ANGELINA JOLIE has launched a scathing attack on Kim Kardashian  – calling her a “witless bimbo” for using Twitter in a misguided attempt to protect Armenians in Syria, say sources.

The battle erupted after the 33-year-old reality star and fiancee of rapper Kanye West urged her 20 million Twitter followers to help save the ancient Armenian Christian village of Kasab, which had been seized by rebels in the Syrian civil war.

But her efforts backfired big-time when supporters of Syrian despot Bashar al-Assad used her tweet to bolster propaganda that the rebels had slaughtered residents and desecrated churches.

“Angelina was far from impressed at the way Kim decided to throw her two cents into such a sensitive issue,” revealed an insider. “She thinks the Twitter account of a reality star is a terrible platform for something so serious, period.”

Kim, who’s proud of her Armenian roots, compared the rebel activity to the early 20th century Turkish slaughter of some 1.5 million Armenians. She urged her followers to Google “what’s going on in Kessab (sic)” and to “get this trending.”

A stream of hysteria followed Kim’s March 30 posting with fanatical Syrian politicians – including Islamists loyal to the terrorist group al-Qaeda – thanking Kardashian for her support!

The insider said that 38-year-old Angelina – a longtime United Nations goodwill ambassador – exploded, fuming: “Who does this witless bimbo think she is? Why doesn’t she stick to reality TV?”

A second source added: “Angelina believes that if Kim was sincere about wanting to help, she’d do it thoughtfully as opposed to sending out half-baked messages to people via social media.”
