Sienna Miller, 44, announces the birth of her third child, weeks after welcoming the baby. Multiple outlets report that the child is her second with boyfriend Oli Green, who is 29. Sources say Miller and Green already share a younger child together, with one daughter previously welcomed whose name has not been widely published. Several reports also note that Miller is a mother to a teenage daughter, Marlowe, aged 13, from her relationship with actor Tom Sturridge.

The Independent and other tabloids describe Miller as expressing strong affection for the newborn as she makes the announcement, while additional coverage focuses on her parental life and timing of the birth. Belfast Telegraph and other outlets confirm the birth occurred, but provide limited additional detail in the provided material. Overall, the reports consistently agree on the main points: Miller is 44, the baby is her third child, it is born to her relationship with Oli Green, and she already has two children from previous relationships.
