The Kardsahians are at it again with members from the MTV cast of Teen Mom. This time it is Kourtney versus Farrah Abraham.

Us Weekly reported that Teen Mom Abraham tweeted that she was shocked Kourtney is pregnant again, along with other insults aimed at the Kardashian. But Kourtney was quick to defend herself.  

Why would I have anything to do with Teen Mom? Kourtney tweeted. I'm 32 years old! I may look young, honey, but don't get it twisted.

Abraham then replied:  Did she not learn anything from Teen Mom? Maybe it's a fake pregnancy like Kim's wedding. SAD.

Scott Disick, 28, the two time daddy-to-be immediately defended his baby mama.We're not teenagers, ya f***ing moron.

But the Teen Mom would not give up. Guess what! Age and money honestly do not change a person's poor choice, Abraham tweeted after the diss. Quit making excuses. 

This is not the first time a member of the Kardashian family got in a row with one of MTV's Teen Moms.

Back in June, it was Kim Kardashian versus Amber Portwood.

Kim took to her blog to write about the dangers of teen pregnancy and how Teen Mom figures are not the people you should idolize!

It seems that shows like Teen Mom are all of a sudden making teen pregnancy seem cool in the eyes of young girls...but girls, these are not people you should idolise! wrote Kardashian.

When I think back to when I was 16, there is no way I would even have considered having a baby.

Having a baby is one of the biggest, and most life-changing decisions a person can make and while I'm not saying that no teen is in the position to raise a child, having a baby so young shouldn't be seen as the trendy thing to do, Kardashian wrote.

Amber Portwood was not willing to take Kim's criticisms lying down.

Last time I checked, Kim Kardashian had a sex tape floating around on the internet and I'm pretty sure she made a lot of money off of it, said Portwood.

She made a sex tape when she was younger and she wants to bash the girls on 'Teen Mom?'

Portwood has a daughter, Leah, and earned $280,000 per season of the series.

There's actually a study that shows since the original 16 and Pregnant aired, the number of teen pregnancies have gone down, Portwood told E! News.

If you read the articles about the show, they do nothing but talk about how the show reveals how hard it is for all of us.

It doesn't glamorize anything. It shows the heartache we've all gone through, she said.

We may be 'celebrities' because our face is out there, but it's only because we've done some bad things. That's not glamorous.
