The American actress, 32, has no children at the moment but has explained she is surrounded by baby talk as two of her best friends are currently pregnant.
"One of them is pretty chilled and the other's like, 'I can’t wait to have a glass of wine!' I love it though…we sit in bed all day, watching movies and ordering food in," she told Red magazine.
Kirsten has hinted at starting a family herself.
"I think 33 is a good age to have your first baby," she continued. Adding about having no concrete plans for marriage or children: "You don’t know what's going to happen in the next 10 years."
The Hollywood beauty previously dated Brokeback Mountain star Jake Gyllenhaal but is now in a relationship with her On the Road co-star Garrett Hedlund, 29, whom she has been going out with since 2012.
Despite potential baby pressure, Kirsten appears at her happiest in her thirties: "I'm so good at chilling out…I’ve become really good friends with relaxing."
