The House of Lies star, 32, wed her fiancé of almost three years in a "no-frills" ceremony on Oct. 16.
Bell confirmed her marriage on Twitter on Oct. 18 saying, "Wife coffee tastes way better than regular coffee in the morning :) @daxshepard1."
Though the couple got engaged in late 2009, they decided to hold off on getting married until same-sex marriage bans were overturned nationwide.
In June 2013 Bell re-proposed to Shepard after the U.S. Supreme Court overturned the Defense of Marriage Act and Proposition 8 was overturned in California.
The couple welcomed daughter Lincoln in March 2013.
Bell currently stars in the Showtime series House of Lies as Jeannie Van Der Hooven and recently finished filming the highly-anticipated, Kickstarter-funded Veronica Mars movie in the title role.
Shepard continues to play Crosby Braverman in season 5 of Parenthood and will also appear in the Veronica Mars movie.
