It seems Mischa Barton did hit up rehab – no pun intended – after her DUI bust in December.  Even though it was denied at the time and her arrest was brushed under the rug, she went.  Why keep it a secret? 

More pics after the hop…

The DUI should have been the secret part, not the rehab to get better.  Why do stars hide their stints in rehab?  Because it may help their image?  Because they don’t want anyone to know they have a problem?  Isn’t that one of the first steps in getting better, though? 

She admits her rehab was a step to prove she took it seriously, she says to Marie Claire via omg.  Does it make you think of her better since she went?  Maybe that’s why she only got probation???
