By Adam S. Levy For Dailymail. An 'embarrassed' Jessica Biel was behind husband Justin Timberlake's recent public apology for his cozy behavior with female co-star Alisha Wainwright last month at a New Orleans bar. Biel, 37, 'encouraged Justin to put out his statement on Instagram because she felt embarrassed by his actions and wanted him to take accountability,' an insider told US Tuesday. The Ely, Minnesota-born beauty, who shares a four-year-old son named Silas with the superstar singer, is 'still united' with Timberlake, 38, in the wake of the incident, the source told the publication. The relationship between the 7th Heaven actress and Say Something singer fell under scrutiny November 21 after Timberlake was seen looking snug with actress Alisha Wainwright, 30, who is his co-star in the upcoming film Palmer, at the Bourbon Street establishment the Old Absinthe House bar.
