Nearly hidden behind a bushy beard and a green baseball cap, Justin Timberlake was spotted in Westwood, Calif., on Friday out and about with fiancée Jessica Biel.
It's a rare sighting of the pair since a source revealed last month that Timberlake, 31, and Biel, 29, got engaged during a vacation to Montana.
But there's still no photographic evidence of the "custom-designed ring."
Biel, who earlier was seen with an apparent wedding band on a movie set, kept her left hand tucked in her pocket.
