Actress Sienna Miller enjoyed a child-free night out on Wednesday as she attended a West End performance of Abigail's Party at London's Harold Pinter Theatre.
The 44-year-old star looked in high spirits as she arrived at the venue wearing an embroidered white shirt paired with flared blue denim jeans, black slip-on shoes, and orange-tinted sunglasses.


The outing comes as Mike Leigh's 1977 hit comedy play Abigail's Party returns to London's West End for a strictly limited run, starring actress Tamzin Outhwaite in the central role of Beverly.
Family Updates and Recent Clues
The theater appearance follows recent hints shared by Miller regarding her growing family with her 29-year-old fiancé, Oli Green. Earlier this month, the actress appeared to confirm the birth of a baby son after posting a photograph showing the three-month-old infant lying in a pram with a blue heart emoji covering their face.
In another photo from the family summer holiday, a makeup-free Miller was seen reading to her daughter, whose face was covered with a red heart emoji. The child's name has never been publicly announced. Miller also shared a close-up photograph of Green during their getaway.

Miller previously announced that she had welcomed her second child with Green in May, and announced welcoming her third child by saying, "It's happened. I have a tiny baby next door." She had revealed her pregnancy in December when she showcased her blossoming bump at the star-studded Fashion Awards. The actress also shares a 14-year-old daughter, Marlowe, with her former partner, actor Tom Sturridge.
Celebrity Guests at Harold Pinter Theatre
Miller was among a star-studded audience attending the West End production on Wednesday night. Presenter Gaby Roslin brought a splash of color to the event in a bright orange shirt paired with blue-lens sunglasses.

Comedian Leigh Francis, also known as Keith Lemon, made sure all eyes were on him in a straw sun hat and a printed T-shirt depicting toy hedgehogs. Actress Angela Griffin opted for an all-blue co-ord ensemble paired with chunky trainers.

Actors Michael Brandon and Glynis Barber also enjoyed the theatrical night out together in central London.

Actress Sarah Parish turned heads in a deep blue wrap dress accented with a brown belt, while actor Daniel Mays and his wife Louise Burton beamed ahead of the show.


Presenter and actress Tina Hobley arrived wearing a green and white striped shirt with a pale yellow skirt, while radio presenter Emma B selected a white and black polka dot dress for the occasion.


Coping With Motherhood and Work
Speaking in May during an appearance on The Tonight Show With Jimmy Fallon, Miller opened up about returning to work just three weeks after giving birth while surviving on "very little sleep."
Reflecting on her return to work while promoting her action movie Jack Ryan: Ghost War, Miller shared the reality of managing a newborn alongside her career.
"It feels like stringing sentences together is a bit challenging," Miller told Fallon. "I'm on very little sleep but I'm madly in love with my baby. It's crazy to be talking words and wearing a dress. What has happened from pajama gate."
When asked by the host which of her children proved harder to look after, Miller recalled a difficult transatlantic flight. "I would have said the teenage girl would be harder to juggle until the transatlantic flight I took yesterday with the toddler and the newborn," she said. "The toddler now wins hands down. It was an absolute disaster. There's no negotiating. I got to the immigration line and just broke down."
