Is the Oscar-winning blonde ready to marry beau Jim Toth already? Rumor has it they're talking about moving in together, at least!

Ms. Witherspoon was spotted leaving a bridal store in Santa Monica on Saturday (buying a gift for a friend) before heading off to a party with her man of four months...

But is she also planning her own nuptials? Reese's romance with Jake never seemed a good fit, but I have a feeling she'd be willing to give marriage another go with Jim. He's the one!
