Sienna Miller and Tom Sturridge have split, ending their three-year engagement, according to The Sun (via Mirror). The couple has a three-year-old daughter, Marlowe Ottoline Layng.

"Tom and Sienna split a few weeks ago but still love and respect each other as friends and parents," a source told The Sun. "It's a very amicable break-up and they intend to remain great friends."

Miller was seen not wearing her engagement ring earlier this month in Ibiza, according to Mirror. She again appeared ring-less on July 10 while taking in a match at Wimbledon.

The 33-year-old actress started dating the 29-year-old Sturridge four years ago. They got engaged in January 2012 after Miller got pregnant.

"It was just a case of them being honest with each other and putting first they are parents," the source said about the couple's decision to break up.

Miller was previously engaged to Jude Law between 2004 and 2006.

The English actress will next star in the film "Mississippi Grind" with Ryan Reynolds and Ben Mendelsohn, out on Sept. 25. She also plays opposite Bradley Cooper in "Adam Jones."
