We haven't seen a T-shirt used as a weapon to this degree since back in the '90s when those "I'm With Stupid" shirts were all the rage. 

Real Housewives of Atlanta stars Porsha Stewart and Kenya Moore clearly aren't pals, and it looks like Porsha's sister Lauren is firmly on her sister's side in this feud.

Porsha took to Instagram on October 18 to post a few photos of Lauren wearing a shirt that we don't think Kenya is going to appreciate. "Awe, look at @lodwill 'Bye Ashy' Tee, too cute #tobeyoung," Porsha's captions the shot. 

As you can see, Lauren is wearing a shirt with the words "Bye Ashy" on it, which refers to Porsha saying that same thing to Kenya on the show in Season 5. 

Indeed, it seems apparent that Porsha and Kenya have clearly not patched things up since Season 5 wrapped. And when Kenya was asked by a Twitter follower in August if she and Porsha are on better terms, Kenya simply responded, "Who?" Ouch!

In fact, their feud continues to get worse. Last month, Kenya was accused of copying Porsha by starting her own hair line, and Kenya had some not-so-nice things to say in response.

And Lauren's "Bye Ashy" shirt reminds us a bit of how a T-shirt played a role in the battle between Real Housewives of Beverly Hills star Brandi Glanville and LeAnn Rimes.

Perhaps all Real Housewives feuds could just be fought using T-shirt slogans from now on?
