Personal life.
Giertz is the granddaughter of architect Lars Magnus Giertz, and niece of his brother Bo Giertz, who was a bishop. Her great great grandfather, Lars Magnus Ericsson, was the founder of telecommunications manufacturer Ericsson, and author Martin Giertz is her second cousin once removed. Giertz and her partner, television producer Nicola Söderlund, had one daughter, Simone Giertz, who is a popular inventor and YouTube creator.
In a 2012 interview, Giertz said that she had been diagnosed with ADHD, which she suspects has influenced her fondness for building and decorating.
