Rihanna slammed long-term rival Ciara for allowing the media to ''play her''.

The 25-year-old pop star hasn't always seen eye-to-eye with the 'Body Party' singer and has taken a swipe at her for always mentioning her in interviews.

Rihanna posted on Instagram: ''Why am I still the main topic of her interviews!!

''She don't be shame tho? How she let em [the press] play her like that everytime?? It's like, 'yea I know you're here to talk about (insert album title) but we wanna talk about a more relevant topic...Rihanna!!! (sic)

She continued: ''Like she sits there and falls for it everytime!!!! #whurrisyopublicist (sic).''

The bitter row between the singers initially began two years ago when Ciara accused the Barbadian babe of not being ''the nicest'' when they met at a party.

Rihanna sarcastically replied: ''My bad ci, did I 4get to tip u? #howrudeofme.(sic)''

The spat between the pair has fizzled out over the past year but Ciara recently re-started the argument when addressing Rihanna on an episode of 'Fashion Police' saying she was ''nuts'' for ignoring her.
