Christina Aguilera has experienced a lot of big changes in her life recently — new baby and now the role of designer muse.

Christina's friend, London jeweler Stephen Webster, is introducing a new sterling-silver collection inspired by the songbird. The Stephen Webster Silver Collection is full of silver rings, cuffs, pendants, and earrings inlaid with gemstones ($343-$3,52, made to look like broken stained glass, and will launch next month at Neimans.

Christina will also be featured in the collection's ad campaign, shot in LA, and set to look Hitchcockian. The first ad will break in the April issue of W, so keep a look out!
