Vicki Gunvalson posted a telling message about "good friends" on Instagram on Thursday.

Vicki Gunvalson Speaks: Is She Quitting 'RHOC' After Season 10?

Although Gunvalson and her co-star Tamra Barney had appeared to reconcile their once-strained friendship just weeks ago, the Real Housewives of Orange County star hinted at a good friend gone bad in the caption of one of her latest posts.

"Good being with 'good friends' here in Orlando," Gunvalson wrote to fans, who immediately wanted to know why she put quotes around "good friends."

Meghan King Edmonds Is 'Desperate' For A Story Line On 'RHOC,' Claims Vicki Gunvalson

Throughout the 10th season of The Real Housewives of Orange County, Gunvalson's friendship with Barney has been up and down, mainly due to the ongoing speculation regarding Brooks Ayers' cancer diagnosis, as well as Barney's newfound friendship with Meghan King Edmonds, who has been extremely vocal about her dislike for the longtime reality star.

In response to fans' questions regarding her "good friends" comment, Gunvalson explained the words were put in quotes “because not everyone is a ‘good friend’ to me.”

On Friday morning, Gunvalson shared a second post, which she captioned, "Me after filming #RHOC this year."
