The "All the Stars" hitmaker was trying to stock up on products from Rihanna's popular cosmetics line at a Calabasas branch of Sephora on 30 April, when the 28-year-old allegedly found herself being racially profiled.
"Lmao (laughing my a** off) Sandy Sephora (sic) location 614 Calabasas called security to make sure I wasn't stealing," SZA posted on Twitter after the rude encounter.
She then quipped, "Can a b**ch cop (buy) her fenty in peace er whut (sic)".
Rihanna has since heard all about the incident, and decided to show SZA some love by treating her to a free shopping spree.
SZA shared a photo of the handwritten message she had received from the "Umbrella" singer on her Instagram Story timeline over the weekend, May 25-26.
It read, "Go buy your Fenty Beauty in peace, sis. One love".
Expressing her gratitude for the kind gesture, SZA captioned the post, "Tanks (sic) Queen," adding a series of heart emojis.
