Slick Woods, who went into labor while walking Rihanna’s Savage X Fenty NYFW Show, praised her “immortal boss” in an open letter for Allure magazine on Monday. The model and new-mom wrote about what the Bajan singer has taught her and how quickly they have become family.

“You introduced me to a more mainstream level of exposure,” Woods wrote in the letter shared on Rihanna’s Instagram. “People loved the idea of Slick, but you gave me countless platforms to let people fall in love with who I actually am. You made inclusivity cool, and that’s revolutionary.”

The model continued, “You have my loyalty until the end of time. My gratitude for the growth, love, and support you’ve put in my life will never subside.”

Rihanna thanked the young model for her letter. “Thank you for these beautiful words. . .You have been just as significant to my platform sis! And you bout to knock motherhood out the park!”
