Gwyneth Paltrow says she simply can’t function in a messy environment, prompting her to go on a “cleaning frenzy” when things are messy. In fact, untidy places often cause the star to lose sleep and leave her no other choice.

She told America’s Harper’s Bazaar magazine: “I cannot function if there is a physical mess around me. If everything is falling apart, I go on a cleaning frenzy…I cannot go to sleep with dishes in the sink.”

The Iron Man actress – who has two children with ex-husband Chris Martin – also revealed to be good friends with Beyoncé and says the singer is surprisingly low-key and shy in her everyday life.

She said: “If you met her and you didn’t know who she was or what she did, it would be inconceivable to you that she was Beyoncé.

Some really famous people, even when they’re off-duty, have this energy that is sort of overpowering. She does not have that. She is so dialed down. She’s the sweetest mother. She’s very shy.

You would not believe she is Beyoncé Knowles. You would be like, ‘No, that was not her.’ And that’s why when I see her perform, I’m like, ‘Oh, s**t, I forgot.'”

Despite being in the public eye for a number of years, she insists she still goes unnoticed while out and about most of the time.

“I’ve learned to navigate it. If I’m somewhere where there are a lot of tourists, then I’m asking for it. But if I go to the market or I’m back-to-school shopping with my kids, it’s not a problem.

Some people ask for pictures, but it’s completely fine. I’m able to be a normal mom for the most part. I’m in (clothing store) Brandy Melville like all the other moms.”
