By now, Cardi B is famous for her extravagant, ultra-long nail looks — but her latest manicure, which she had done for her new footwear collection with Reebok, might just be her lengthiest look yet. (She's even giving fellow nail-art queen Kylie Jenner a run for her money.)

The "WAP" rapper, who celebrates her 28th birthday today, Sunday, October 11, took to Instagram to unveil the news about her upcoming collaboration with Reebok. The announcement post features a photo from the campaign in which Cardi B appears to be in an all-blue laundry room-like space — complete with a crystal-studded washer and dryer set, a blue carpet, and an array of items behind her in the same hue.
