Sandra Bullock has revealed she is taking a break from work because she is "burnt out".
The 57-year-old star of The Lost City has made three movies in the last two years and admitted she is exhausted.
Bullock told The Hollywood Reporter: "I don’t want to be beholden to anyone’s schedule other than my own.
"I’m so burnt out. I’m so tired, and I’m so not capable of making healthy, smart decisions and I know it."
She added that she did not know how long her time out from working would be.
Bullock admitted that work had become a "crutch" for her.
She said: "It was like opening up a fridge all the time and looking for something that was never in the fridge. I said to myself, ‘Stop looking for it here because it doesn’t exist here. You already have it; establish it, find it and be okay not having work to validate you.’”
Earlier this year the mother-of-two mentioned she wanted to take some time off work to spend with her two children, Louis, 12, and Laila, 10.
She said: "I am just going to take some time to be a mom.
"I love stories that show the imperfection of love within families and communities. I would love to continue doing that when I’m done being a mom. I’ll get back to it. I don’t know when. Probably when they’re teenagers, solidly 16- or 17-year-olds."
Bullock adopted her children as a single mother in 2010 and 2015 after splitting from her husband Jesse James, due to his infidelity.
She is now dating photographer Bryan Randall, but said she had no interest in tying the knot again.
She told Red Table Talk: "I am someone who went through the divorce process.
"We share two beautiful children - three children, his older daughter. It's the best thing ever. So, I don't want to say do it like I do it, but I don't need a paper to be a devoted partner or a devoted mother. I don't need to be told to be ever-present in the hardest of times. I don't need to be told to weather a storm with a good man."
