Public relations agent Kyle Schaffler spilled the beans on his Twitter page, writing, "I love that no media outlets know about the Justin Timberlake and Jessica Biel engagement. Benefits of working PR."

Justin and Jessica reunited after a brief breakup in March. The two were thought to have rekindled their romance over 4th of July weekend when Timberlake was spotted visiting his ex in Toronto, where she was filming "Total Recall." The pair began dating in 2007.

If it's true they're engaged, it comes on the heels of Timberlake's ex, Britney Spears, announcing her engagement to Jason Trawick.
