Why Sienna Miller has ‘regret’ over 14-year-old daughter’s unexpected red carpet appearance

Sienna Miller said she felt “slightly concerned” after her 14-year-old daughter, Marlowe, made an unexpected red carpet appearance at the “War” premiere in London last Wednesday. “Marlowe didn’t actually walk the red carpet with me. She came with her friend. My mom was also there,” the actress clarified on SiriusXM’s “The Julia Cunningham Show” this week. “It was five seconds at the end where she, like, came to give me a hug and totally mogged me,” she added.

Getty Images for Skys World Premiere of WAR Miller, 44, explained she has some “regret” about the situation because both she and Marlowe “didn’t expect” the public’s reaction to the stunning teenager. “I think I’m going to be sending her away to a nunnery for the next four years until she can emerge as an actual adult,” Miller quipped, before reiterating, “It was not what was planned. It was not intentional.” The “Factory Girl” star noted that while her daughter is indeed “extraordinarily beautiful,” her looks are “the least interesting thing” about her. “She’s so clever and she’s so funny and she’s still my little girl,” Miller said about Marlowe, who she shares with ex Tom Sturridge. “I don’t know that we’re going to be doing more red carpets. She, kind of, popped on at the end. It was five seconds.” Miller explained that the pair (seen here at the event) didn’t expect the public to comment on Marlowe’s looks. lounisphotography / SplashNews.com Miller said that while Marlowe is indeed “extraordinarily beautiful,” her looks are “the least interesting thing” about her.

She wishes I would brush my hair. However, Miller said that ever since the family moved to London in 2023, Marlowe’s “starting to appreciate the undoneness.” Community Guidelines Welcome to the Page Six Community!
