Actress/singer Jennifer Lopez is expanding her presence on Tv after landing a new role as an undercover cop in an upcoming drama.

The star will play the lead role in Shades of Blue, a new crime show focusing on a single-mother detective who is recruited to work for the Fbi.

Jennifer Salke, of America's NBC Tv network, says, "Jennifer is an extraordinary talent and life force, and we're delighted to be in business with her... We're especially excited that Jennifer is returning to her acting roots... and we know that she will create this complicated character in a vivid way that will breathe new life into the cop show genre."

Production is expected to begin next year (15).

Lopez began her career on Tv as a dancer for sketch show In Living Color, but she has most recently been seen on the small screen as part of Tv talent competitions such as American Idol and her own Latin show Q'Viva! The Chosen.
