Sienna Miller and Tom Sturridge Break Up

It looks like it’s over between Sienna Miller and Tom Sturridge.

According to The Sun (via The Mirror), the couple has ended their three-year engagement. Together since 2011, Sienna, 33, and Tom, 29, are parents to daughter Marlowe Sturridge, 3. The breakup reportedly happened “a few weeks ago,” and they are said to be on good terms post-split.

Sienna, Tom and Marlowe were most recently seen on vacation in Ibiza two weeks ago. A Sun source said the American Sniper actress and Robert Pattinson‘s BFF “still love and respect each other as friends and parents,” adding, “It’s a very amicable breakup and they intend to remain great friends.”

“It was just a case of them being honest with each other and putting first the fact they are parents,” a source told The Sun, which broke the breakup news.

However, we have learned that Sienna and Tom had been fighting a lot recently. “It seemed like it was only a matter of time,” an insider explains.
