Originally, Jen posed for a pic with her stylist Chris McMillan and she seemed super excited about her new 'do, but she soon revealed to Elle UK that the shorter style was sort of a necessary evil.
"It wasn't for a role. My hair went through a phase," she told the mag. "I did this thing called a Brazilian and my hair did not react really well to it."
"The minute I cut my hair I want it back. Always. It's a guarantee. I'm trying really hard to love this one," she confessed.
Unfortunately, it sounds like she just wasn't able to convince herself that she loved her shorter strands as she was just spotted wearing what seems to be some brand new hair extensions.
We have to say, we like this look a lot better, but we also know the feeling when you've done so much damage you have no choice but to chop the stressed tresses.
Do you like Jen's hair better long or short?
