Reese Witherspoon will kick off 2011 as a betrothed woman.

Insiders tell Us Weekly that the actress is engaged to Jim Toth, a Hollywood agent who proposed over the weekend. Simply put, "they are extremely happy," Witherspoon's rep says.

Witherspoon and Toth went public with their relationship in March. Previously, she had been married to Ryan Phillippe, with whom the star has two children. She also dated Jake Gyllenhaal for two years.

We wish this couple many years of happiness!
