Colin Firth's Wife Admits to Affair with Alleged Stalker Livia Giuggioli and Firth had accused Italian journalist Marco Brancaccia of stalking them, a claim that he denied. “A few years ago Colin and Livia privately made the decision to separate. During that time Livia briefly became involved with former friend Mr. Brancaccia. The Firths have since reunited.” "Subsequently, Mr. Brancaccia carried out a frightening campaign of harassment over several months, much of which is documented. For obvious reasons, the Firths have never had any desire to make this matter public.” According to The Times, Brancaccia said that Giuggioli "wanted to leave Colin for me" because their marriage had "been over for years." Firth and Giuggioli have been married since 1997 and have two children together.
