Model/actor Oli Green may be 15 years her junior, but that doesn't seem to be keeping Sienna Miller's new man from stepping into the role of dad. Miller, who told Elle that she had some of her eggs frozen when she turned the big 4-0, announced in August 2023 that she is pregnant. She did not say whether or not she used one of those eggs, nor did she specifically name Green as the father. However, Miller has been seeing the actor/model since 2022, so we think it's safe to say he is part of the equation in some way. And, as mentioned before, the pair were hanging with Miller's ex Tom Sturridge at Wimbledon in 2023, so it seems as though they are all one big, happy family.
Green comes into the relationship without any children of his own, but Miller, who has a child from a previous relationship, should be able to give him plenty of pointers. Of all the roles she has played in her career, it is the role of mom that she cherishes most. She told People in 2019, "When you are raising a child you see aspects of your character in that person, reflected back, and it's the most loving, intense relationship that I have."
Miller hasn't said a ton about Green, but she has offered hints about their connection. She told British Vogue in 2022, "there's a misogyny that is ingrained in men of my age and older that I don't see in [the] generation below."
