Jamie Bell and Evan Rachel Wood seem to be getting serious and fast. In fact, could they already be engaged after dating for less than one year?

While leaving Papaya King in Hollywood over the weekend with her beau, Ms. Wood flashed some bling on her ring finger while getting into a cab.

A source close to the couple recently told Us Weekly, "They have been shopping for rings for at least a month."

Bell, 25, and Wood, 24, dated for a year back in 2006 and recently reconnected. When they first dated five year ago, the two stars both got matching tattoos. The couple met on the set of Green Day's "Wake Me Up When September Ends" music video back in 2005.

This would be Wood's second engagement. In January 2010, the actress was briefly engaged to rocker Marilyn Manson.

Reps for both stars have not yet answered our requests for comment.
