It takes an extra special cause to get Sam Winchester to shed his shirt while hanging out with Oliver Queen!

'Supernatural' star Jared Padalecki has just posted an adorable picture on his Facebook page that shows him and 'Arrow' actor Stephen Amell shirtless. The photo was taken this weekend, when the two TV stars hung out together.

The photograph was not just a blatant excuse to show off their rock hard six pack abs. Jared Padalecki had captioned the picture with the link to his site, "Stephen Amell and I lost our shirts L Maybe we should grab one from the represent.com/Jared relaunch!!! Only 2 days!!!!"

At the recent San Diego Comic-Con, Jared Padalecki has admitted during the 'Supernatural' panel that he suffered from depression and asked fans to help raise funds. He and costar Jensen Ackles have launched 'Always Keep Fighting' to help raise awareness about depression, and sold tshirts with a picture of Jared Padalecki and the slogan.

Stephen Amell was happy to help out his friend by posting a similar shirtless picture on his own Facebook page. "Stay Sunday Strong. My buddy Jared Padalecki wants you to Always Keep Fighting. https://represent.com/jared," he captioned.

Jared Padalecki is set to return as Sam Winchester in the CW series 'Supernatural' Season 11. The new season will find Sam teaming up once again with his brother Dean Winchester (Jensen Ackles) as they try to save the world from The Darkness that was unleashed when they erased the Mark of Cain.

Stephen Amell recently made news when he announced on Twitter that he will never grow a goatee for 'Arrow,' saying that the show can go on for up to 11 seasons but he will never wear a Green Arrow goatee. He later retracted his statement by saying that he will grow the beard once 'Arrow' reaches its sixth season.
