The 44-year-old revealed her new 'do on Monday while running a few errands in LA. Earlier this month she told Vogue.com: "It was kind of spur-of-the-moment.
"It's simple, it's really simple, that's for sure. But I'm always one of those girls who does a big old chop just to get it really healthy, to repair all the [damage from] hair colouring and stuff like that. And I just got bored, honestly. It's fun to change it up once in awhile."
In a recent interview Jen admitted she'd rather shave off all her hair than have the Rachel cut ever again.
When asked in a recent interview on The Kyle And Jackie O Show, "Would you rather have the Rachel haircut for the rest of your life or shave your head once?" Jen opted for going bald. Let's hope she doesn't feel the same about this look in a few weeks time.
