Gossip Girl star Leighton Meester, the face of Vera Wang's Lovestruck fragrance, has teamed up with the designer to support DKMS Americas, the world's largest bone marrow donor centre.

Wang has designed a t-shirt featuring the slogan 'Share the Love', which will be given as a gift-with-purchase when customers buy a product from the Lovestruck collection at Macy's from today. Meester will also appear in a promotional ad with Kerri Mullen, a leukaemia survivor who was saved by a bone marrow donation from a DKMS donor.
