The Oscar-winning actress walked down the aisle to "Here Comes the Bride," according to the magazine.

Witherspoon, 35, and Toth, 40, became engaged in December after dating for almost a year. She has two children — Ava, 11, and Deacon, 7 — with ex-husband Ryan Phillippe. The two divorced in 2007 after seven years of marriage.

Witherspoon will next be seen in Water for Elephants, coming out next month.
