Kourtney Kardashian has been verbally abused by a drunken fan.

The 32-year-old socialite was spending the July 4 holiday in New York's exclusive Hamptons district with her 18-month-old son Mason when a passer-by screamed "bitch" at her.

Writing on her twitter page, Kourtney explained: "I love how I was walking nicely w my son in the Hamptons and a drunk w***e yelled BITCH because I waved at her instead of saying hi. #classy (sic)"

Up until then, the 'Keeping Up With the Kardashians' star had been enjoying a cruise with son Mason and boyfriend Scott Disick.

She tweeted: "Happy 4th of July babies! Nothing like a Hamptons cruise with my family. (sic)"

However, Kourtney isn't the only member of the Kardashian clan to have encountered problems with members of the public.

Last year, her sister Kim had a drink thrown over her while filming scenes for her reality show 'Kim and Kourtney Take New York'.

Kim said: "I want to address this because everyone has been asking me if I'm OK after the bar fight last night. I'm totally fine, guys.

"Last night, Kourtney, Scott, Khloe and I went out to a bar to have a fun night on Khloe's last night in New York. A drunk male fan came up to me and asked to take a picture, and I obliged, but his girlfriend, who was also drunk, got a little out of hand."
