Seth Rogen's Fiancée Flashes Engagement Ring by His Side at Green Hornet Premiere — Check Out Her Diamond!

Seth Rogen kept his fiancée Lauren Miller close as they hit the red carpet at tonight's premiere of The Green Hornet in LA. Cameron Diaz looked sexy and tan in a tight red dress at the screening, but Lauren had her own eye-catching accessory on her left hand. Her diamond engagement ring stood out against her pink number as she posed with her real-life leading man. Seth popped the question in September and shared his embarrassing nudity-filled proposal story on Conan a few months back. He has a long week of promotional duties ahead of The Green Hornet's release on Friday, and luckily he has his proud partner by his side for his big night.
