On-again/Off-again Celebrity Couples

Jude Law and Sienna Miller

This tumultuous love affair has always made headlines. They started dating in 2003 (while Law was still married) and got engaged a year later, but then came Nannygate and everything fell to pieces. After three years apart (which was also chockfull of tabloid  fodder), they rekindled their romance, that is, until this past February.
