The actress and fiancé Martyn LeNoble tied the knot on Saturday, E! News confirms.
"Christina Applegate and Martyn LeNoble exchanged vows...surrounded by family in a private ceremony at their home in Los Angeles," her rep said.
Their rings were designed by Neil Lane, and the bride wore a gown by Maria Lucia Hohan.
The star and the Porno for Pyros bassist have been together for nearly four years and became engaged on Valentine's Day in 2010. Applegate was previously married to actor, writer and director Johnathon Schaech for six years, until their divorce in 2007.
Congratulations to the newlyweds!
