malibu house party independence day Reese Witherspoon beach ocean tattoo hat shorts

Reese Witherspoon and her family enjoyed the holiday weekend in Malibu, but thanks to the ocean breeze, we were able to catch a glimpse of the 35-year-old star's stomach tattoo.

Jim Toth's wifey used to have a tattoo of a blue star in the area, but it appears that she transformed her old ink into a something a bit bigger.

Over the weekend, Reese kept her tummy completely covered with a black one piece swimsuit. Who knew Ms. Witherspoon had such a rebellious type of tattoo? We're lovin' this sexy side of the Southern belle.
