They famously fell out in 2011 after Ciara claimed that she "wasn't the nicest person" but it looks like Rihanna may have reignited her feud with the R'n'B star.
The Diamonds singer's BFF and personal assistant Melissa Forde has taken a very public dig at CiCi's new single, Body Party.
Earlier this week, Ciara gave fans a sneak peak of her latest offering from her forthcoming album by singing the track in her hotel bathroom.
Dressed in the Givenchy dress that she wore for a Paris Fashion Week party, she belted out the lyrics a cappella. The video was posted online.
Making an indirect reference to the footage, Forde posted a photo of her and Rihanna laying down on a bathroom floor with another friend. The caption read: "#BodyParty (bathroom acapella version) #London."
An unimpressed Ciara quickly responded to the photo, tweeting: "Don't have time 4 the silliness. Grow Up and Do Something Positive with ya selves for once. God Bless."
RiRi and Ciara's have been enemies since the star complained about Chris Brown girlfriend during an interview
"I ran into her[Rihanna] recently at a party. She wasn't the nicest. It's crazy, because I've always loved and respected what she's done in fashion. It wasn't the most pleasant run-in," with told E! News.
The comment did not go down well with Rihanna and sparked a nasty Twitter row between the pair. At one point Ciara even threatened a face-to-face confrontation.
Ciara seems to have already but the spat behind her by premiering her new single along with the steamy artwork.
