Business or pleasure?

Justin Timberlake was back on set with “Palmer” co-star Alisha Wainwright just days after the two were spotted holding hands.

Both Timberlake and Wainwright were dressed casually as they got back to work for their movie in New Orleans on Monday.

The “Can’t Stop the Feeling” singer, who is married to Jessica Biel, was photographed out with Wainwright earlier this week where he was seen holding hands with the co-star. Wainright, who plays Timberlake’s love interest in their film, also appeared to rest her hand on the pop star’s knee.

However, sources told Page Six that they are just friends.

“There is 100 percent nothing going on,” a Timberlake source said.

The 30-year-old crooner was reportedly not wearing his wedding ring.

Timberlake and Biel, 37, have been married since 2014. They share 4-year-old son Silas.
