Following the end of her relationship with Friend, Knightley was introduced to musician James Righton by a mutual friend in 2011, according to People. The two connected immediately and started dating not long after. In May 2012, the couple took their relationship to the next level and got engaged.
One year later, in May 2013, Knightley and Righton tied the knot in an intimate ceremony, with just 11 people present, in Mazan, France, as reported by British Vogue. Righton later gushed about the special day to NME, saying, "It was the greatest day ever, it was fantastic. We're still high from it. It was about two weeks ago, it was a big party."
A few years into their marriage, the pair welcomed their first child together, Edie, on 25 May, 2015, and later had a second child, Delilah, in September 2019. Though Knightley and Righton keep their personal life under wraps, the two occasionally attend public events together, like fashion shows and launch parties.
