Both met on the sets of the Daany Boyle movie in 2008 and fell in love soon after.
After dating for almost six years, the couple has decided to part ways.
Both have been very comfortable about their relationship and also displayed it openly giving various red carpet appearances frequently. But from quite sometime, they have not been seen together and reportedly, Frieda celebrated her 30th birthday without Dev.
The 'Immortals' actress was, instead, spotted hanging out with aspiring actor and son of Indian businessman Vijay Mallya, Siddharth.
