Sienna Miller is reportedly engaged to her boyfriend of one year, Lucas Zwirner.
The 38-year-old actress sparked engagement rumours when she stepped out in New York over the weekend wearing a diamond ring on her ring finger.
The 21 Bridges actress, who has been dating the 29-year-old literary editor Lucas since 2019, is said to have taken their relationship to the next level with the loved up couple ''excited'' for what's to come.
Speaking to Us Weekly, a source said: ''They're so in love."
''Her daughter has a nice and close relationship with Lucas too. They're excited for this new chapter.''
Miller, who has seven-year-old daughter Marlowe from her previously relationship with her former fiancé Tom Sturridge, was also previously engaged to fellow actor Jude Law whom she dated on and off between 2003 and 2011.
Speaking about her desire to get married and have more children, Miller recently remarked: "Yes, I would love to have more children. I would love a daughter as well. I think I would be open to getting married, yes."
She also heaped praise on Zwirner, saying: "He's not an actor! He's not famous. It's nice and settled and happy…
"It is interesting to be in a world that is not the one I am in. The art world is very new and fascinating, and very intellectual, which I love."
