Brittany pulled a perfect celebrity trick and left the public "clueless."

The actress married her boyfriend, 37-year-old screenwriter Simon Monjack, weeks ago in a private ceremony. The couple was able to keep their nuptials a secret until they arrived at a Playboy magazine party at the Kentucky Derby wearing wedding bands.

Now, Brittany's publicist has confirmed that the petite star is a "Mrs."

The rep told "E! News" the pair wed "several weeks ago in a very intimate ceremony."

And Brittany is one happy bride. According to celebrity jeweler Neil Lane, she was given two engagement rings. He told "Access Hollywood, "The couple couldn't decide which ring they liked best, so they bought both. She got two big platinum and diamond cushion-cut whoppers - one big white and one big yellow."

Brittany, who rose to fame in the '90s teen flick "Clueless" and appeared in "Sin City" and "Don't Say A Word," met "Factory Girl" writer Simon after her two previous engagements broke up.

The star also dated Ashton Kutcher before he married Demi Moore.
