Sienna Miller had fans seeing double when she shared rare photos of her eldest daughter, Marlowe, to celebrate her 14th birthday on Tuesday.
The actress, 44, shared two recent photos of the teenager in a sweet post on social media, and her followers were blown away by their uncanny resemblance.
One image shows Marlowe sitting in a chair and holding up her birthday candles, while the second photo features her showing off her unique style, rocking baggy jersey shorts, a cropped shirt, bug sunglasses, and cowboy boots.
A third image was a heartfelt throwback of Sienna gazing at a sleeping baby Marlowe. Instead of words, she kept it simple and captioned the post with a red heart emoji.
Unlike her mother's blonde locks, Marlowe has long brown hair, but there's no denying the family resemblance.
"She looks exactly like you!!! So beautiful," one fan commented. A second said: "Happy bday to your gurl! She reminds me so much of you."

Sienna shares Marlowe with her ex-boyfriend, Tom Sturridge, whom she dated between 2011 and 2015. They welcomed their daughter in 2012, and despite the end of their relationship, they have remained friends and are often seen co-parenting Marlowe.

"It's happened. I have a tiny baby next door," she told E! News. "It feels like stringing sentences together is a bit challenging. I'm on very little sleep but I'm madly in love with my baby."

The actress posed for photos with her fiancé on the red carpet at London's Royal Albert Hall in a see-through dress made of white tulle with a bustier-like neckline.
A few months after Sienna's announcement, the star's 47-year-old sister Savannah also revealed she's pregnant with her "miracle baby."

Before announcing she was expecting, Sienna candidly opened up in April 2022 about entering her '40s and feeling pressure over whether to have more children.

She continued: "Biology is incredibly cruel on women in that decade – that's the headline, or it certainly was for me. Then I got to 40 and I froze some eggs. Having been really focused on the need to have another baby, I'm just like, if it happens, it happens. That kind of existential threat has dissipated."
