Jensen Ackles, best known for playing Dean Winchester in the cult series "Supernatural," is celebrating his 38th birthday on Tuesday, March 1. Ackles and the rest of the cast have so much fun shooting the series that they are not ready to say goodbye even after eleven years.

The bond the cast has with each other is evident from their fun Instagram posts and the panels they host at various fan conventions. They are always with each other, even if "Supernatural" is on a break, and their love makes the fans fall in love with them all over again.

"Supernatural" has also given the cast personal gifts along with professional ones, especially for Ackles' TV brother Sam aka Jared Padalecki. He met actress Genevieve Cortese, who played the role of the demon Ruby, on the sets of "Supernatural" and later married her. The foursome – Ackles, Padalecki, Cortese and Ackles' wife Daneel Harris – are often seen spending time together with each other, sometimes even having family fun-times with their kids.

In celebration of Ackles' 38th birthday, here some of his rare and adorable photos with his real and reel family:
