Yep, that's him. And her.
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.
