jogging breakup Reese Witherspoon doesn't seem to be the type of person to look backwards, but she did on a jog with a pal yesterday!

She's been keeping a low profile since her split with Jake last week, but Sunday Reese ventured out for a run in Brentwood. She's usually pretty stoic-faced, but we can totally see a glimpse of heartache on her adorable face.

Awww, even celebs get the breakup blues!
