Reese Witherspoon has become the latest star to join the race to the altar in 2011 as the actress and her Hollywood agent boyfriend Jim Toth are engaged. The star began dating Toth at the beginning of 2010 shortly after she and Jake Gyllenhaal split, and now her publicist has confirmed the Oscar winner is planning a second trip up the aisle. 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.
