Jessica Chastain

The 'George & Tammy' star met the country music singer backstage at the CMA Awards.

In the meantime, we'll be catching up on George & Tammy on Showtime. Jessica tells John & Tammy, "I met Miranda Lambert at the CMAs and she offered me bourbon in a red solo cup, and I'm obsessed with her. The hosts of John & Tammy in the Morning ask, "You have a dinner party, there are 6 people at the party. It has to be people that are going to bring it, you know?" She says, "I want it to be a wild dinner party." But the Oscar-winning actress revealed she recently met a current queen of country music, and the singer clearly made an impression.
