Miller had her first child, her now 10-year-old daughter named Marlowe, with her ex-partner Tom Sturridge, whom she dated from 2011 to 2015.
Reports about her latest pregnancy emerged last month, with People magazine photos showing Miller, who starred in Netflix’s Anatomy of a Scandal last year, wearing a bikini on a beach in Ibiza with what appeared to be a baby bump.
Speaking to the Telegraph earlier this month while launching his new collection with Marks and Spencer, Miller hinted
to the reports but refused to confirm them.
“I’m looking for stretchy pants and very loose sweaters,” she said when asked what was on her fall shopping list.
“You’re asking me at the wrong time in my life.”
Asked if her daughter Marlowe, 10, now wants to borrow her mother’s clothes, she said: “It’s actually the other way around, I borrow her clothes.
“Not at the moment because I have a slightly different shape… but she has cool hoodies.”
Miller added that red carpet appearances can make her feel anxious.
“It can be fun if I wake up and feel safe or indifferent,” she said.
“But I’m sure there’s always a little bit of anxiety in all of this. Getting ready is fun, but stepping on the red carpet is not something I look forward to.”
