Jessica Biel In Oscar de la Renta - 2013 Grammy Awards

Justin Timberlake, who hasn’t released an album in nearly seven years, performed his new single ‘Suit and Tie’ with Jay-Z before premiering another new song, ‘Pusher Love Girl’, on Sunday night at the 2013 Grammy Awards.

His biggest fan in the crowd was of course his wife, Jessica Biel.

Shunning the daring dress code associated with the event, Mrs Timberlake wore a beautiful Oscar de la Renta Pre-Fall 2013 gown.

The navy one-sleeve gown was styled with black Casadei ‘Blade’ t-bar sandals and gorgeous statement earrings.

Even though there aren’t any full-length pictures of Jessica in her gown, I have to say this is one of her best looks: classic, refined and very elegant.
