The duo reportedly started dating in Sept. 2004 after first meeting when the Black Eyed Peas filmed an episode of the TV show Las Vegas, which Duhamel starred in.
Fergie and Duhamel got engaged in the winter of 2007, after three years of dating.
A year after getting engaged, the couple tied the knot on Jan. 10, 2009. Nine months after tying the knot, allegations surfaced claiming that Duhamel had been unfaithful, but the couple stuck together.
In February 2013, the couple announced that they were expecting their first child together.
Six months later, Fergie gave birth to a baby boy named Axl Jack Duhamel on Aug. 29.
Four months after the birth of their son, the couple was spotted out on a date in Santa Monica, Calif.
During a March 2015 interview with E! News, Fergie said that she and Duhamel had agreed on having two kids.
"We negotiated early on to have two kids," she told us.
