Looks like Meri Brown and Robyn Brown’s relationship is stronger than ever! Over the weekend, the “Sister Wives” stars shut down rumors that they were feuding after the mothers of Kody Brown’s children snapped an adorable selfie together while celebrating Robyn’s birthday.

The tweet comes after In Touch magazine revealed on Thursday that Robyn reportedly had known about Meri’s emotional online affair -- a scandal that Kody’s first sister wife had previously addressed on Monday, Oct. 5, in an interview with People magazine.

"During an emotional and vulnerable time earlier this year, I began speaking with someone online who turned out to be not who they said they were," Meri said, admitting to getting catfished by a woman impersonating a man. “I never met this person and I regret being drawn into this situation, but I hope because of it I can help others who find themselves in similar circumstances."

The incident only became more shocking when Robyn’s friend Kendra Pollard-Parra dished to In Touch magazine that the TLC star knew her fellow sister wife was having an online rendezvous after fans reportedly brought it to her attention.

“I brought it up to Robyn and we looked and we saw there was definitely a relationship going on,” Pollard-Parra told the outlet.

This left fans questioning the relationship between Robyn and Meri -- something viewers have inquired about ever since Meri revealed during the Season 5 finale of “Sister Wives” that she was divorcing her husband of 24 years for Robyn.

Meri explained that the reason she decided to divorce Kody was so that Robyn could legally become his wife and, hopefully, that would allow Kody to adopt Robyn’s children from her previous relationship.

“I’m not going to lie -- it is a little bit scary for me doing this divorce,” she confessed during the emotional episode, “and having it really be for nothing as far as the possibility of not being able to adopt the kids.”

After Meri admitted she was relinquishing her title of Kody’s legal wife, viewers began theorizing that Kody and Robyn swindled her into the situation.

“I am so tired of hearing comment after comment about Kody and Robyn putting me up to this or forcing me into it, or Robyn ‘taking’ my position in the family,” Meri responded to skeptics on Twitter. “No position was given up, no position was taken.”

Meri continued to express her love for her sister wife, adding she would divorce Kody for the sake of Robyn and the happiness of Robyn's children all over again if she had to.
