Renee Zellweger lived out of a suitcase at the height of her acting career and didn't unpack until she was 41

When asked to give her younger self some advice, Renee told the Guardian newspaper: "Girl, slow down. Moving from place to place, constantly living out of your suitcase - I never unpacked until I was probably 41."

Renee went on to insist she has no regrets about taking a six-year break from her movie career.

She added: "There was a lot to treasure ... I scrutinised myself. And because I wasn't taking care of myself in my 30s, I didn't make great choices all the time ... It's really easy to forget yourself in the mix."

It comes as Renee prepares to launch her fourth Bridget Jones movie - 'Bridget Jones: Mad About the Boy' -in cinemas in February and the actress admits she can empathise with the character over the pressure on women to get married and have children.

Renee - who was married to musician Kenny Chesney for five months in 2005 and has no kids - added: "To choose not to have children isn't that exceptional, is it? I think it's quite common [these days]."

She added of the character - created by writer Helen Fielding in a newspaper column in the 1990s: "Isn't that a cool thing that Helen created this character that people want to talk about for 30 years?

"I think people see themselves in her imperfections, vulnerability and fear. Her authenticity and transparent humanity make it easy for folks to feel that 'I know her'."
