AceShowbiz - Speaking of a forgiving lover, one cannot forget to mention Sienna Miller. The British actress, who got engaged to Jude Law in 2004 after dating for several months, was cheated on by her fiance and "Alfie" co-star with the nanny of his children in 2005. After he issued a public apology to the "Factory Girl" actress, the pair attempted to work through their issues and stayed together until they separated in November 2006.
A few years later, however, they seemed to still have feelings for each other as it was reported that they rekindled their romance in December 2009. Their second attempt to be together didn't work though, as they split up for good in 2011. In 2016, Sienna confessed that she has no hard feelings for her ex despite his past affair, telling Porter magazine, "We don't see each other that much. I care about him enormously."
