Ashley Jacobs is firing back at Kathryn Dennis over the tweet she posted after last nights dramatic season 6 finale of "Southern Charm".

Jacobs shocked everyone when she made a surprise appearance at Patricia Altschul'sparty during Wednesday's season finale of the hit Bravo show, and Patricia's decision to have her escorted out of the gathering sent tempers flaring.

After the episode aired, Dennis jumped on the moment to take a dig at Jacobs by posting to Twitter a BTS shot of the moment and wrote, "HA #aboveit."

Dennis also shared a video on Twitter of writing, "what y'all missed," which appears to show how she and some of her friends reacted to Ashley's departure from the shindig.

Dennis even tried to circulate the hashtag, "#byeashley."

In response to Dennis, Ashley told The Blast that she felt her co-star was being "petty."

Ashley also told us, "It was sad to hear the news of her mother's passing, I would think at a time like this, this pettiness would be beneath her."

The star says she may understand why Dennis has been lashing out, explaining, "As a hospice nurse, I know everyone grieves in their own way. To each his own."

The beef between the two reality stars goes way back, and they don't appear to be close to making up anytime soon.

Ashley is also dating Dennis' baby daddy, Thomas Ravenel, and has been involved in the bitter custody dispute between the two.

Things have gotten so bad, that even Ashley's ex-roommate has gone to court in support of Dennis after allegedly obtaining private text messages from the reality star.
