Leslie Odom Jr. Sings Justin Timberlake On SMASH

NBC's musical drama series SMASH is set to feature a cover of Justin Timberlake's current worldwide hit "Mirrors", taken from his remarkable new THE 20/20 EXPERIENCE album, on an upcoming episode.

Leslie Odom Jr. performs the heartrending ballad live on camera, harmonizing with himself on the tricky intervals of the R&B flecked tune before the video cuts away to a montage of scenes showing the behind-the-scenes goings-on of SMASH in a new extended clip posted on YouTube.

Upcoming SMASH guest stars Daphne Rubin-Vega and Lillias White make appeareances in the self-shot cam video, while we also glean glimpses of Katharine McPhee, Megan Hilty, Debra Messing, Christian Borle, Jeremy Jordan, Anjelica Huston and the rest of the SMASH crew.

Perhaps most exciting for die-hard SMASH fans is the footage of new production numbers - one featuring a wall of green laser-lights, no less - which can be glimpsed in this new clip, as well as some stolen shots of BOMBSHELL's glamorous opening night celebration.

Most of all, Odom Jr. impresses with his passionate delivery of a true Justin Timberlake gem.
