Dressed in a sexy white gown, the Oscar-winning actress was joined on the red carpet by co-stars Leighton Meester, Garrett Hedlund and Tim McGraw.
Meanwhile, Gwyneth and Faith Hill say they have big plans for their offspring to get married to one and other.
The two became firm friends after Gwynnie starred alongside Faith’s hubby Tim on Country Strong, and now hope that they will one day become family.
In an interview with InStyle magazine, the pair joked that they want Gwyneth’s four-year-old son Moses to hook up with Faith’s 9-year-old daughter Audrey.
“Moses…we might really become a family when he marries Audrey!” Gwyneth joked.
“Don’t you just love our babies?” Faith added.
Country Strong is scheduled to be released January 7, 2011.
