The supermodel has been inked with an anchor design.
It joins a pair of swallows on her lower back, a quarter-inch heart on her left hand by the thumb and a crown on her left shoulder.
Kate, 34, is currently dating The Kills guitarist Jamie Hince.
Anchor body art symbolises stability and often shows commitment to a relationship.
Other stars with the design include Canadian singer KD Lang and Gossip singer Beth Ditto.
