This could shape up to be a monumental week for Reese Witherspoon.

The stunning blonde actress who just seems to get more gorgeous with age turned 35 years old on Tuesday. As if that wasn’t enough of a boost, the rumor mill is buzzing with reports that she and her boyfriend Jim Toth are planning on tying the knot on Saturday in a (sorta) secret weekend wedding. There haven’t been any confirmations or denials of the nuptials, but Reese tends to be tight-lipped about those things.

One thing is for sure: Reese has been working out big time lately. Almost daily, photogs have snapped her mid-run around her Los Angeles neighborhood.
