The Transformers hunk spends his spare time hand-crafting necklaces and gems for friends and family, and even wears his own designs.

Duhamel has been spotted sporting a pendant he made to represent his union with his singer wife Fergie.

When asked about the piece he wears, he explained, “It’s this gold charm with an F and a J intertwined (for Fergie and Josh). I made it.

“I once took a class in college, got all the carving tools, did wax casting. Now I make gifts. It’s fun, like whittling.”   [Source]
