Who says chivalry is dead?

Sienna Miller hit the Live By Night red carpet on Wednesday in London, England, wearing a lovely black and cream-colored Lanvin gown, but inevitably got cold while posing in the 50-degree weather. Her co-star, Ben Affleck, came to her rescue and loaned her his black overcoat while she chatted with the press. Meanwhile, Affleck made do with his navy blue suit jacket.

It was exciting,” she gushed. "I have a mental photo that I will hold onto!”
