Jennifer Garner's one of the most approachable celebs we encounter on a regular basis - just make sure you don't get too close to her daughter Violet!

We spotted the Alias actress doing a little grocery shopping at the Farmer's Market yesterday.

As she left, a crowd of photographers gathered around her. One of them ended up in Jen's personal space - and got chewed out for his lack of respect!

"What is your deal?" Jen snarled. "I'm with a little child!"

Needless to say, everyone stepped off - after all, nobody wants to be on the end of a Sydney Bristow ass-kicking!
