Olivia Wilde recently opened up about end of her 8-year marriage to Italian prince Tao Ruspoli.

The 28-year-old old actress, who filed for divorce in March 2011, told Amanda de Cadenet that separating was "the scariest thing I've ever done."

"You don't want to break up with someone, you dont want to end a marriage, especially if you really like the person -- you just know that something's off so you try to change everything else," she said on "The Conversation" last Thursday. "We basically built a new house and it was perfect -- just a glorious house -- and the day it was finished was the day I knew it wasn't the house."

Wilde, who tied the knot with Ruspoli on a bus in 2003 (when she was just 18), is currently dating SNL star Jason Sudeikis.

It's not the first time the actress has dished on her divorce. In March 2012, she told Town & Country magazine that divorce made her feel like "such a failure" and admitted to turning to food after the split.
