Los Angeles - Rihanna says she got her attitude from her mother.
The Stay singer - who recently ended her on/off relationship with Chris Brown - praised her "beautiful" mother Monica for teaching her how to be a strong and independent woman in a touching Mother's Day tribute.
Writing on her Instagram profile alongside a picture of Monica to mark the occasion on Monday, the 25-year-old beauty wrote: "Her attitude Rihanna, she got it from her mama!!!.... Happy Mother's Day beautiful!! What a lucky little bitch I am to have come from you!
"You showed me real strength, how to be independent, how to love and be loved, not to judge people or their situations, how to forgive, how to learn from every mistake I make, how to be hospitable, how to do my makeup, cook, clean, not to lower my standards for anything or anyone!"
Rihanna also mentioned her late grandmother Dolly in the message, adding: "DOLLY taught you so well, I can only imagine how incredibly proud of you she is!!!
"I am who I am because that's all I've known!! Thank you for all that you've endured to make sure I got here, with a smile!! I could never repay you, you're PRICELESS!!! My gem!!! #mommy #happymothersday #mamasgal #mynumber1 (sic)"
Rihanna is scared of her mom
Earlier this year, Rihanna admitted the only person she fears in the world is her mother.
She previously said: "I'm not afraid of any person in this world, but my mother, I'm terrified of her. She called me two days ago and reeled me in about two naked pictures [my pal] Melissa [Forde] put up on Instagram, a sneak peek from a photo book she's making about me.
"She went crazy on me, I was like, embarrassed. I felt like I got my ass whipped in front of my class at school! She humbled the fuck out of me."
