Elisabeth Rohm starred for four years as Serena Southerlyn on Law & Order.

Since then, the beautiful actress has chosen to drop in for brief appearances on the occasional hit show. She guest-starred on The Mentalist last season; she's booked on next week's 90210 season premiere.

And now she's coming to Heroes!

NBC has confirmed that Rohm will appear in the season's eighth episode. She'll portray a character named Lauren Gilmore. That's all we know about the role for now.

Heroes comes back to the air with the "Redemption" volume on September 21. Check out an extended trailer for it now!
