Jessica Biel and Justin Timberlake's Beach and Bikini Vacay

EXCLUSIVE

Jessica Biel's got us drooling again, and wishing we were Justin Timberlake ... again.

Jessica flaunted her toned bod during a Caribbean vacay with Justin. It's the first time we've seen her rocking the hell out of a bikini since giving birth to 1-year-old son, Silas.

Speaking of toddlers, Justin looks like he's salivating too ... and ya can't blame him.
