The R&B twosome got into a heated Twitter feud back in 2011 after Ciara said she had an unpleasant "run-in" with the singer and RiRi "wasn't the nicest" on an episode of E!'s Fashion Police.
Of course, that didn't sit well with the feisty pop star, who proceeded to engage in an all-out Twitter war with Ciara, dissing the singer and posting, "My bad Ci, did I forget to tip you?" on her micro-blogging page.
Although the twosome eventually made up, it seems like Ciara has reignited the fire, and she recently addressed her rocky relationship with Rihanna in an interview with Wild 94.9 radio.
"I don't have beef with anybody, but I'm not going to be disrespected either. I wish her well," she kindly stated, before taking a dig at Chris Brown's gal.
"I don't know what her problem is. I think she's nuts right now, like, whatever's going on, because for me, it doesn't make any sense," she said of the "Diamond" singer's controversial behavior. "She has a lot of good things going on with herself. A lot of good things I've always said I've been happy for her. I don't get it. I really don't, but I wish her well. I wish her positivity."
And if that's not enough, Ciara also took to Twitter to share her thoughts on the 25-year-old singer.
"I am baffled. The obsession really makes no sense. This is getting out of hand...," she posted. "Somebody please point her in the right direction, cuz she clearly needs love and affection..:)," she added, clearly referring to the lyrics in Rihanna's "Love Song."
Hey, whatever you say, Ci. Place your bets below on the time it takes for Ri-Ri to respond.
