Earlier this week, Justin Timberlake, 38, was spotted getting close to new co-star Alisha Wainwright, 30, during a night out.
The singer now reportedly "feels guilty" about holding hands with his co-star and is trying to make it up to his wife Jessica Biel, 37, according to The Sun.
A source has told E! News that Timberlake knows how important his family and relationship with wife Biel is and they are trying to move past it.
The source said: "They are downplaying everything and trying to laugh it off as nothing.
"But it was definitely inappropriate and something that would make any wife uncomfortable."
