After tying the knot, Cameron Diaz and Benji Madden appear to be settling into the newlywed life just fine. They have even already double-dated with the in-laws.

After getting engaged less than a month ago, it appears the couple kept their wedding plans a total secret--until now.

Cameron Diaz and Benji Madden have only been dating for the past seven months, but it appears as though the couple is ready to take the next step; marriage.

The 42-year-old attended the Academy's Hollywood Costume luncheon Wednesday in Los Angeles and looked classy in a black knee-length dress, but most of the attention was placed on her gold ring.
