Chris Brown has no problem speaking on his relationship history with Rihanna, however, she is not happy about it.

Brown opened up about his past with Rihanna in his documentary, which was released earlier this month.

"We just became friends and kicking more," Brown said in the Chris Brown: Welcome to My Life documentary. "Nothing too serious but we just had a good understanding of each other."

He continued to explain the moment they decided to be an exclusive couple.

"I remember staying over her house, and I was like, 'Man, what are we doing?' She was like, 'What do you mean? And I was like, 'I am always over here and we like each other obviously, let's just do it. Let's just be boyfriend and girlfriend.'"

While this would be music to millions of girls' ears, Rihanna had a different response, Brown added.

"She was like, 'You ain't serious! I don't think you want to do that... You ain't ready.' And I was like, 'I am, I am ready for real... I think I love you!' She was looking at me like, 'What? Did I say the word?'"

The two ended up being in a whirlwind romance until things went south in February of 2009.

Now, nearly eight years later, Rihanna is reportedly upset about Brown being so open about one of the most romantic moments of their former relationship.

"Rihanna is pretty pissed Chris is bringing up their old drama again," one insider told Hollywood Life earlier this month. "She never wants to be put in that position again, and she still carries pretty deep scars, as much as she tries to act otherwise. The experience itself was hugely traumatic, but the way it played out so publicly added yet further to the trauma."

"Rihanna wants to be known as this fierce, independent, strong woman - not be tainted with this weak, victim label. She's struggled to get close to anyone and has developed deep trust issues when it comes to men," the source added.

As for that horrific night, which Brown abused Rihanna, it reportedly started after Brown told Rihanna he messed with another girl. Things got worse when the girl came up and said "hello" to Brown at a pre-Grammy party in early 2009.
