The couple — who met on the set of "Step Up" back in 2006 — announced their separation Monday with a joint statement.
"We have lovingly chosen to separate as a couple. We fell deeply in love so many years ago and have had a magical journey together. Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now," the couple said.
They continued, "There are no secrets nor salacious events at the root of our decision — just two best-friends realizing it’s time to take some space and help each other live the most joyous, fulfilled lives as possible. We are still a family and will always be loving dedicated parents to Everly."
The couple concluded by saying. "We won’t be commenting beyond this, and we thank you all in advance for respecting our family’s privacy."
Dewan was actually spotted running errands on Monday around Los Angeles. She appeared to be wearing a wedding band, but not her engagement ring.
The news of their split was first reported by PEOPLE.
Tatum and Dewan were married on July 11, 2009 in Malibu, California. Their daughter, Everly, is 4-years-old and will turn 5 this May.
