Sienna Miller and Tom Sturridge are demonstrating an unconventional approach to post-relationship family life, with Sturridge recently announcing his engagement to Alexa Chung, who is also a close friend of Miller's.
Miller and Sturridge, who share a 14-year-old daughter, Marlowe, have maintained a close and amicable relationship since their separation in 2015. This friendly dynamic has extended to their new partners, with Miller engaged to actor Oli Green. The two couples have been seen together at public events, including Wimbledon in 2022, where they posed for a group selfie.
In a 2023 interview with Vogue, Miller described their blended family gatherings as "very loving and cozy and great," highlighting their unique success in navigating these relationships. She noted the unconventional nature of their co-parenting arrangement, stating in a 2019 interview with Elle UK that "it's not like there's a structure for custody. We make it work."
Sturridge and Miller were together from 2011 to 2015, getting engaged and having their daughter before their split. Despite ending their romantic relationship, they have remained close friends, often spending time together to co-parent Marlowe. Miller previously told Harper's Bazaar that Sturridge remains her "best friend in the entire world."
While Miller went on to have other relationships, including a brief engagement to Lucas Zwirner, she met her current fiancé, Oli Green, in 2021. Sturridge confirmed his relationship with Chung the following year. Miller expressed her approval of their relationship, telling Vogue UK, "I'm really happy for them. It's genuinely lovely."
Chung recently confirmed her engagement to Sturridge, which had been rumored since mid-2023. This marks Chung's first public confirmation of the engagement after years of speculation. Miller has also spoken positively about Chung's role in Marlowe's life, referring to her as her daughter's "stepmum" and praising her fashion sense.
This blended family dynamic challenges traditional notions of post-divorce relationships, with Miller and Sturridge appearing to prioritize their daughter's well-being and maintaining a supportive environment for all parties involved.
