The "Transformers" star was seen Saturday morning running errands around Los Angeles and made a pit stop to grab some coffee.
Duhamel, who was wearing jeans, a sweater and a backwards hat, was also out with his 5-year-old son, Axl.
As we reported, Black Eyed Peas singer Fergie finally filed for divorce after nearly two years since breaking up. It's unclear why the two waited so long to make it official, but their statement after splitting up made it clear they were taking things slow so that their family could adjust.
"To give our family the best opportunity to adjust, we wanted to keep this a private matter before sharing it with the public. We are and will always be united in our support of each other and our family," the stars said in a joint statement when they finally revealed the split.
Fergie has not yet been seen since the filing.
