Freida met Dev on the set of Danny Boyle's hit 2008 movie 'Slumdog Millionaire', before continuing to date for nearly six years. Dev is now dating 'Lion' co-star Tilda Cobham-Hervey.
In an interview with Red magazine, Freida says she is proud of Dev, reports dailymail.co.uk.
She said: "At the end of the day he's a fellow actor and my friend. I've seen the hard work he's put in, and seeing it pay off (by winning the BAFTA) is the most beautiful thing. How could I not feel proud? He was fantastic in that film 'Lion'."
Freida, who has previously said the pair broke up after she had a 'quarter life crisis', said she learned from the relationship.
The actress said: "People come and go and everyone teaches you something. You need to embrace the good and bad, the ugly and beautiful. I'm not a love guru. I don't have any tips on how to keep a break-up friendly. Just be open and honest."
