Jessica Simpson feels "grounded" when she's barefoot.
The 35-year-old beauty loves wearing high-heels but has admitted she chooses to ditch the platform shoes when she feels herself getting nervous.
When asked for 25 unknown facts about herself, she shared: "When I'm nervous, I take off my shoes so I can feel grounded. But I still won't wear flats."
During the open interview, the fashion mogul also revealed her writing style is dependent on her mood and that she detests bad grammar.
She added: "When I write, I use different colours of ink and styles of handwriting, depending on my mood.
"One of my pet peeves is writing with incorrect grammar."
Jessica - who has two children, three-year-old Maxwell and two-year-old Ace - also admitted she is a "homebody", despite having moved tens of times.
She shared: "I have moved more than 20 times in my life, but I'm still a homebody."
However, her and her children have a regular routine as the star cooks for them most nights although she admits she was less obedient as a child.
She explained to Us Weekly magazine: "As a kid, I left space camp because the ice cream was dehydrated. But I still dream of being an astronaut."
