And by lets loose, we mean Reese Witherspoon skipped the flat iron at some point over the last 24 hours!

On Friday a chipper Reese hit the gym in Brentwood, and the Oscar winner was all smiles when X17 photographers snapped her photo. And she has every reason to be stoked! Her latest film, Wild, which hits theaters on December 5, has been getting amazing reviews, and there's even buzz that the 38-year-old thespian could snag another Academy Award.

While her career is clearly back on track, one can't really say the same about Reese's once squeaky clean image. When asked about her disorderly conduct arrest at the BFI London Film Festival last week, Reese told reporters, "I think it was a moment where people realized that I wasn't exactly what they thought I was. I guess maybe we all like to define people by the way the media presents them, and I think that I showed I have a complexity that people didn't know about."

It certainly threw us for a loop! But she is usually pretty sweet with photogs, so she can't be THAT terrible, right? Or is it all just an act?
