Posting a screen shot in her Instagram account of the TMZ.com video in which Barnes, 35, said on Saturday they were friends "and we'll see where it goes from there," Rihanna, 27, captioned it with hashtags including "she's not that into you," "she's not into you at all," "she's never even met you," "this actually hurt my feelings" and "defamation of character," among other bon mots.

The Grammy-winning singer has been photographed twice recently vacationing with Formula One champion Lewis Hamilton, 30, leading to romance speculation.
