Jude Law & Bikini-Rocking Sienna Miller Vacation in Ibiza (PHOTOS)

On-again (and rumored to be engaged again) couple Jude Law and Sienna Miller are in the midst of a hot summer vacation on the party island of Ibiza, Spain.

New shots show a black bikini-sporting Sienna holding Jude’s hand en route to an inflatable dinghy ride with another tourist couple. A gentlemanly Jude even helps his lady onto the shaky boat!
