With Valentine's Day just around the corner, Rihanna is already working on her love letters. The first recipient will not be A$AP Rocky, nor the couple's adorable sons, RZA and Riot. Instead, it is her fans who are the focus of attention. Their first gift was sealed with a bright pink kiss.

On Thursday, January 11, Rihanna unveiled her latest campaign for Savage X Fenty. It was a Valentine's Day-themed photoshoot featuring pink underwear and even pinker lips. Although the images are strictly for her lingerie brand, fans couldn't help but compare what lipstick the 35-year-old is wearing to MAC's iconic Candy Yum Yum shade. Nevertheless, there was no doubt that Rie was wearing Fenty Beauty. So the inquisitive turned to the perfect person to ask: Priscilla Ono, global makeup artist for Fenty Beauty.

"When your panties match your lipstick," Ono wrote in an Instagram post featuring the campaign.

According to the artist, the enigmatic product is Fenty Beauty's limited-edition Iconic Velvet Liquid Lipstick in the shade Pink Limosine, a bright hot pink with blue undertones. The matte lipstick features a creamy, whipped texture that "envelops the lips in intense color in one precise swipe" and leaves the mouth feeling plump without drying.

Although the mystery was solved, fans were not completely satisfied. (In particular, how did the Grammy winner's slightly darker lip liner come about?

"When do we get lip liner?" one follower commented on Ono's post." Someone please find a lip liner and let me know lol," another wrote.
