The actress began dating LeNoble in 2008, a year after she divorced her first husband Johnathon Schaech (07).
And now the Samantha Who? star is preparing to wed again following the musician's marriage proposal in February (10).
Her rep confirms to, "Christina Applegate and musician Martyn Lenoble are engaged."
