Did you favorite call it quits this year?

It’s over for Sienna Miller and Tom Sturridge.

The couple, who have been together for four years, have reportedly called it quits. Ending their three-year engagement, Miller, 33, and Sturridge, 29, are said to be still on good terms despite breaking up a few weeks ago.

“They were in a bit of a rough patch for awhile,” an insider tells Us Weekly. “Their schedules on top of raising a child started to get to them.”

The twosome first started dating in 2011. They became engaged when Miller became pregnant with daughter Marlowe, 3.

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