Ben Affleck Shows Off His New Buff Body As He Celebrates 4 July With Jennifer Garner And His Daughters

Errrm, last time we checked Ben Affleck wasn't exactly skinny but he certainly wasn't this buff either. Someone has been hitting the gym. Hard.

One word: guns.

The bulked up star was spotted with his wife Jennifer Garner and two daughters, Violet, 6, and Seraphina, 3, at a Fourth of July parade near their Los Angeles home.

The acting couple ditched the usual Hollywood glamour and kept it low key and casual in jeans and t-shirts for their family day out.

There was one tiny omission from their day though - their four-month-old son, Samuel.

Despite only welcoming his son into the world in February, Ben is said to be keen to start planning for another child as soon as possible - his missus less so.

A source told US Weekly: "Jen is happy with three now that she has a boy... [but] Ben wants four."
