Anyone hoping for a reconciliation between Gretchen Rossi and Alexis Bellino should brace themselves for disappointment -- it seems the ex-best friends aren't ready to bury the hatchet just yet. Things have been tense between the Real Housewives of Orange County costars ever since season 7, when Rossi accused her pal of being "pretentious." And Bellino, it appears, is still holding a grudge.

The drama was reignited on Thursday, July 25, when Bellino started responding to several fan tweets about Rossi being a "bitch" on the Monday, July 22, episode of the Bravo reality show. "I don't even get [why] Gretchen was mad at you," one viewer tweeted at Bellino.

"It's been 2 1/2 years & she has never said a reason," Bellino replied. "It's because I was disposable & she chooses friends of convenience." Later, Bellino added that she was hurt when Rossi "ganged up" on her with the other women. "She was my friend for 2 1/2 years & NEVER told me [she had an issue] til it was the cool thing to do," she tweeted.

Other fans joined in -- some in defense of Rossi -- and then Rossi herself entered the conversation. "So not true," she retorted. "I tried to tell u in many different ways but u never listened, so I had to be a little more direct."

"I never had an issue with u!!" she added. "I said I know your heart, but these girls don't and sometimes u come across this way! Why do u refuse to hear what I actually said?"

As shown in Monday's episode, the ex-friends attempted to work things out recently by meeting up for lunch -- but things didn't go as planned. While Bellino wanted to "hug and make up," Rossi seemed reluctant to just forgive and forget. However, during Thursday's Twitter fight, she said she wanted to put the past behind her.

"I was ready to move on!" Rossi tweeted at Bellino. "But you couldn't even recognize your wrongdoings as well or say you're sorry. You weren't all innocent in all this, A."

"Funny how it's all good when it's on G's time -- that NOW we can move on...when last episode she wouldn't think of it," Bellino fired back.
