Renee's random acts of kindness

Renée Zellweger was spotted having a quick snack at NYC's Porter House while pouring over a stack of birthday and thank you cards.

"I'm working and traveling and so busy I haven't had time to send thank yous," she told the Cindy Adams column at the NYPost.

As if hand-writing nice notes wasn't enough, when the Oscar winner learned that a table of seven across the restaurant was celebrating a birthday, she quietly picked up their check on her way out the door.
