Trend alert! Last week they were peeing on airplanes, but this week, Hollywood's biggest celebrities are saving lives. Notebook star Ryan Gosling kicked things off yesterday when footage hit the Internet of him bravely intervening in a New York City street fight. And it was quite a melee: As the video above shows, the two brawlers were locked in shirt-pulling, painting-grabbing battle, with pleas from bystanders falling on deaf ears. Finally, with one fighter in the midst of strangling the other, the Gos steps in to calmly separate them. Notice that, as he pushes one away from the other, Ryan selflessly drops a grocery bag on the ground, sacrificing his own earthly concerns (we hope there weren't chips in there) in the name of peace.

Gosling would probably have been this week's biggest hero — if not for Kate Winslet. The Academy Award winner was vacationing at Richard Branson’s home in Necker Island when a giant-ass fire broke out in the middle of the night.
