She's new on the beauty block, introducing her Fenty Beauty make up line just this month during a global promotional tour.

But when Rihanna saw an Instagram post that appeared to take aim at her new business, she couldn't help but throw in her two cents.

The B**** Better Have My Money singer commented 'still ashy' and 'shook' underneath a photo posted by rival brand Make Up For Ever.

Shady: Fenty Beauty creator Rihanna left two comments on a post by Make Up For Ever after they implied her line was not the first to feature 40 foundations on Instagram Wednesday

Fenty Beauty has been lauded in the industry for including 40 shades of foundation for all different skin tones, but on Wednesday Make Up For Ever posted a photo showing their own variation.

The caption that joined the photo appeared to be what set the 29-year-old singer off.

It read: '40 shades is nothing new to us. Since 2015, the #ultraHDfoundation released 40 shades for everyone’s unique skin tone understanding the difference between red and yellow undertones.'

Tipped off by her loyal fan base, Rih left her comments which were caught by a fan site before thousands of replies piled in mimicking the Barbadian-born beauty's words.

The Rihanna Navy was quick to notice when the superstar's remarks disappeared from the comments section, causing many to believe that Make Up For Ever deleted them to avoid the embarrassment of being called out by Rihanna.

After launching Fenty Beauty during New York Fashion Week earlier this month, the Work singer made appearances in London, Madrid and Paris to make sure her international fans could get in on her latest swag.

Rihanna, whose full name is Robyn Rihanna Fenty, launched the beauty line in her own name.

This was news to causal followers of the star , as they remained in the dark about the meaning of her beauty brand name.

Rihanna, born in February 1988 in Saint Michael, Barbado, shares the Fenty last name with her two brothers, Rorrey and Rajad Fenty.

She also has three other siblings—two sisters and one brother—born before her father, Ronald Fenty, married her mother Monica.

The singer has always gone by her middle name throughout her career, ever since the release of her debut album Music Of The Sun in 2005.

Now, the last name is sent to be durably associated with Fenty Beauty since the beauty brand has made headlines for its wide range of inclusive shades, which has earned rave reviews from albino people used to not finding beauty products matching their skin tone.

Having risen to fame as a singer, Rihanna recently confessed to The Times that she had wanted to release her own collection after being inspired by her mother's beauty looks in her youth.

She explained: 'It’s a lifelong obsession. I used to watch my mum put her make-up on — all the funny faces she’d make in the mirror.

'I never understood what she was doing, until I got older and fell in love with make-up myself.'
