Rumours have been swirling all month about the release date of Beyoncé's sixth studio album, and on Thursday, the superstar gave fans a taste of what could be to come — in the form of her new fashion line, Ivy Park. The activewear collection will hit stores and online worldwide on April 14, and Bey, who makes a stunning appearance on Elle's May cover, dropped an inspiring video to help launch her new endeavor. And because no Beyoncé video would be complete without a cameo from her 4-year-old daughter Blue Ivy, the little one is featured in between scenes of her mum running on the treadmill, dancing in a studio, and swimming laps. If you blink, you might miss the sweet moment when Beyoncé carries Blue — clad in Ivy Park gear — on her back through a park.
