Katy Perry (in Vera Wang) was on hand at Cipriani Wall Street in New York City to honor Vera Wang for her work supporting DKMS at the the 7th Annual Delete Blood Cancer DKMS Gala. “I’m just honored to be honored,” Wang told InStyle.com before taking the stage to accept accolades for her Share the Love Campaign with Leighton Meester, as the two teamed up to promote and sell a T-shirt with her Lovestruck fragrance with proceeds going directly to DKMS, an organization that raises awareness for blood cancer and empowers people to become bone marrow donors. “It’s impressive how many lives they save!” The evening was filled with musical performances by Jill Scott and country group Lady Antebellum, as well as inspirational speeches, including a video message from Meester, who couldn’t be in attendance. “As thankful as I am, as truly blessed and grateful that I can be to be part of the DKMS family, I can say that I am mostly motivated by the survivors. The survivors are my heroes,” Meester said in her video. To learn more about how you can become a donor head to deletebloodcancer.org. Plus, click the photo to see more.
