Getting back into pre-baby shape is often one of the most difficult things for new mothers to pull off, but you wouldn't know it from the way that some Hollywood moms sport bikinis and tight dresses in no time.

Of course, it helps when you're able to afford someone who manages all of your meals and exercise, but these hot mamas still put in the hard work to get their bodies back into A-list form. In honor of Mother's Day, check out our roundup of 10 celebrity moms whose bodies (and exercise regime) put us to shame!

It was shocking enough to find out that Reese Witherspoon, one of America's sweethearts, was arrested for disorderly conduct two weeks ago, but now the video of her getting handcuffed and put into a squad car has hit the web -- and it's even funnier than we thought!

With her husband Jim Toth already in handcuffs, Reese goes on a major tirade, demanding to know what's going on. "I am a U.S. citizen, and I am allowed to stand on American ground and ask you any question I want to!" she tells the police officer.

Check out the entire video (yep, "Do you know my name?!" quote included) after the jump!
