Hmmm…we wonder who she's referring to!
The post showed a quote that read, "I hate when ex's say.."I'm here if you need me. Where the f-ck were you when we were together and I needed you."
While the "Stay" singer hasn't come at and actually directed the war of words at Brown (or any other exes), it's hard not to imagine who she might be talking about.
The singer also let her true feelings show when she broke down in tears during her Diamonds World Tour stop in France. RiRi thanked fans for their support and composed herself before singing her final song of the evening.
