Ciara's daughter Sienna wants to be just like her mom.

On Thursday, Oct. 31, the singer, 39, showed off her daughter Sienna Princess' Halloween costume as the 7-year-old adorably dressed up as her mom on her Out of This World tour.

Sharing a carousel of costume pictures on her Instagram, Sienna can be seen rocking an all-red look comprised of cargo pants, a zip-up tee, Nike sneakers and a large crown. In one sweet snap, the mother-daughter duo stand together in their matching looks and long blonde hair.

"I asked SiSi who she wanted to be for Halloween and she said me!" the proud mom of four shared. "I can’t tell you how much this means."

"My baby girl went on tour with me and by the end she had every detail locked!" she continued in her caption. "Lil SiSi as Big CiCi. My sweet Sienna Princess Wilson 🥰🖤🎤"

Ciara and husband Russell Wilson share Sienna, Win Harrison, 4, and Amora Princess, 9 months, while the singer is also mom to Future Zahir, 10, whom she welcomed with her ex-fiancé, Future.

Wilson, 35, recently revealed that he's "ready" for baby No. 5 with his wife after she shared a string of Instagram photos in which she was wearing an all-black leather look — complete with a bralette, mesh top and a gold lion embellishment.

Ciara captioned the photos with the word "Lioness," and seemingly the set of snaps got Wilson thinking about what's next for the couple.

"I'm ready when you are," the Pittsburgh Steelers quarterback commented under the post, apparently referring to having another baby with his wife of eight years. "We can name him Cinco," he added.
