AceShowbiz - Justin Timberlake and Jessica Biel put on a united front on Monday night, February, 03 as they made their first public appearance since the singer was photographed looking cosy with co-star Alisha Wainwright.

The "SexyBack" hitmaker faced criticism in November (19) when he was photographed holding Wainwright's hand, while his "Palmer" co-star put her hand on the married singer/actor's knee during a night out in New Orleans, Louisiana.

Timberlake later issued a statement online insisting that "nothing happened", but expressed regret at his "strong lapse in judgement" and shared his sorrow for putting his "amazing wife" through "such an embarrassing situation".

But on Monday, the couple showed they have well and truly put the incident behind them as they posed for pictures at the season three premiere of "The Sinner" in West Hollywood.

While Timberlake opted against walking the red carpet with his wife, the couple beamed from ear-to-ear as they were snapped at the after-party.

Biel remains an executive producer on "The Sinner", while only appearing in the first season. The third series of the show, starring Matthew Bomer, premieres in the U.S. this week.

Timberlake and Biel wed in 2012 and are parents to four-year-old son Silas.
