While the reports have not been verified, it is reported that Pitt was not shocked to learn about the new development.
The Allied actor is said to have always known about Jolie's soft spot towards her former co-star Leto.
He made his film debut in How to Make an American Quilt (1995) and received critical praise for his performance in Prefontaine (1997).
Leto played supporting roles in The Thin Red Line (1998), Fight Club (1999) and American Psycho (2000), as well as the lead role in Urban Legend (1998), and earned critical acclaim after portraying heroin addict Harry Goldfarb in Requiem for a Dream (2000).
Just as former couple Brad Pitt and Angelina Jolie's divorce drama has come to rest, rumours of the actress dating her Girl, Interrupted / Alexander co-star Jared Leto have surfaced.
