HBO's Post 2014 Golden Globe Awards Party - Red Carpet

Holy hair, Hayden Panettiere! It’s been a long time since she was a little girl on Ally McBeal, and she’s officially outgrown the teenage image that we fell in love with on Heroes. We’ve been loving her grown-up style lately (remember that badass Brides Magazine cover?), and thanks to her makeup artist’s Instagram feed, we just got a sneak peek at her super sexy new haircut. The choppy layers make it one of my favorite celebrity bobs in a long time, and from the look on her face in this photo, she seems to be happy with it, too. I’m going to go ahead and say she looks like Rachael Leigh Cook in her heyday (think Josie and the Pussycats) and that’s not a compliment I give out lightly.

So who’s she with? E! has all kinds of juicy info about the man behind Hayden’s cut. According to their website,

The actress—who just last week confirmed she is expecting her first child with fiancée Wladimir Klitschko—turned to Jennifer Aniston‘s hairstylist Chris McMillan for her new ‘do. …  McMillian has famously given Aniston some very stylish bobs over their nearly two decades together. Most recently an asymmetrical version in November of last year. He also was the man behind Kim Kardashian‘s bridal hairstyle from her nuptials to Kanye West last month.

Even though it makes a lot of sense that super rich and well-known people would only trust their hair with the best of the best stylists, it’s kind of adorable to think about celebrities getting their hair done by the same people. Think of all the gossip you let slip when you’re relaxing in a salon chair. Along with knowing who has a weird shaped scalp and who doesn’t condition often enough, McMillian is probably the gatekeeper to all kinds of insider information about celebrities. How can I hire him? Just be the star of an incredibly popular TV series? Cool.

We can’t wait to see how Hayden styles her new cut! We can always count on her to look awesome, and it’s been fun watching her transition into a gorgeous, classy adult.
