The 37-year-old actress earned rave reviews from fans and critics when she filled in for Jimmy Kimmel on his late-night series earlier this year and while she relished the experience, Kristen suggested it may be too soon for her to make a full-time switch into the world of TV presenting.

During a Reddit Q&A, Kristen explained: "I've thought about a show...but Jimmy is a good friend and I see how its ALOT more work than many think it is. So I'm not quite ready for that yet. (sic)"

Kristen's humorous and laid-back approach to the show was warmly welcomed by TV viewers, and the blonde beauty has cited her commitment to fitness as being the key to her optimistic outlook on life.

Asked about her secrets to happiness, the Hollywood star explained: "Go outside, take deep breaths on a walk, WORK OUT, always work out. Get your heart rate up and get the endorphin's you deserve. (sic)"

Despite this, Kristen admitted last month that she and her husband Dax Shepard used to constantly argue.

The married couple were always bickering between themselves during the early stages of their romance, according to the 'Frozen' star, who revealed that her husband was responsible for them turning a corner in their relationship.

Kristen - who married Dax in 2013 - explained: "When we first met, we fell madly in love and I love the dramatic exit. There is nothing I crave more.

"The first year, you are working out your kinks. I loved it.

"We'd get in a fight, because we would fight a lot, and I'd, like, yell something then slam the bedroom door, then I'd slam the front door, then I'd get in my car and then I'd skid out the driveway and I would sit around the corner in my car and it felt so good and I realised how incredibly toxic it was only after he pointed it out."
