Christina Aguilera looks stunning in the new photos to celebrate Macy's 150th birthday. The songstress appears before a wall covered with white roses, dressed in a cream bodice and burgundy dress adorned with green leaves. She grabs roses to match her attire. Other stars who have posed for famous photographer Mark Seliger include fashion designers Calvin Klein, Tommy Hilfiger and Martha Stewart. The magazine with the awaited-pics will hit stores on October.
