Reese Witherspoon Wedding RingNewlywed Reese Witherspoon stepped out of her Brentwood, Calif., gym yesterday, flashing her brand new platinum wedding ring.

The simple band was a nice addition to the 4-carat diamond engagement ring she got back in December when her now-husband, Jim Toth, proposed.

The pair were married just days after Witherspoon's 35th birthday at her Ojai, Calif., home, surrounded by family and friends, many of whom are A-list celebrities. Alyssa Milano attended as well as Scarlett Johansson with new beau Sean Penn on her arm.

After a brief honeymoon with her new hubby, the mom of two didn't take long to get back into her normal routine.
