Witherspoon and actor Ryan Phillippe divorced in 2008. The actress joins LeAnn Rimes, Natalie Portman, Hugh Hefner, Ginnifer Goodwin and Jason Mraz among the celebrities who have announced engagements in the last week, and unconfirmed reports suggest singer Lily Allen has also accepted boyfriend Sam Cooper's proposal over Christmas.
Witherspoon spoke about wedding earlier this year to EW, saying "My mom always texts me, like, 'Are you getting married?' I'm like, 'Mom, come on! You would know if I was getting married.' "
