Jennifer Lopez fans are getting loud about her latest hair transformation.

The “On the Floor” singer shared a set of behind-the-scenes pics from her upcoming movie Kiss of the Spider Woman on Instagram Sept. 14, in which she donned a platinum blonde updo paired with bright red lipstick—and the dramatic makeover quickly drew comparisons to another pop star’s signature style.

“Thought this was Gwen Stefani at first glance,” one user commented, while another asked, “What in the Gwen Stefani is this?”

Even Natasha Bedingfield admitted to seeing the resemblance between the two.

“Omg you look like @gwenstefani,” the singer wrote, adding, “Love you sis.”

Despite the similarities, Jennifer, 56, noted that her new look was all part of embodying her character in the musical drama, which hits theaters Oct. 10.

“Stepping into the role of Aurora felt like dancing through the golden age of cinema,” she captioned the post, “with all the glitz, glamour, and a whole lot of dancing.”
