Sam Rockwell and Leslie Bibb credit their relationship success to ''good sex''.

The couple have been together since 2007 and, as well as making sure they speak openly to one another, they also think getting intimate is a great way of keeping their bond strong.

Asked on the red carpet at the Screen Actors Guild (SAG) Awards on Sunday (21.01.18) for their relationship tips, Sam said: ''Communication.''

Leslie added: ''Good sex.''

Her partner laughed as he agreed: ''Communication and good sex.''

The couple also think it's important to make one another laugh.

Leslie, 43, continued: ''And a healthy sense of humour.''

Her partner replied: ''Humour is very important. She's very funny.''

Later in the evening, the 49-year-old actor took home the Outstanding Performance by a Male Actor in a Supporting Role for his portrayal of a racist police officer in 'Three Billboards Outside Ebbing, Missouri' and praised his partner in his acceptance speech.

He gushed: ''My beloved Leslie Bibb who puts up with me. I love you, baby.''

Sam also joked about his first taste of acting thanks to his parents, claiming he quickly realised those who went into the profession were ''nuts''.

He said: ''My mom and dad were actors. They dragged me to rehearsals at ACT when I was a little baby and I slowly realised that these people are nuts. I love actors and I love my mom and dad.''
