Then Nathan Scott was your typical high school jock who had a talent for getting mixed up in some bad situations.
Now After executive producing an adventure reality series with his brother and former co-star Stephen Colletti -– yep, the guy from "Laguna Beach" -– Lafferty booked a role on NBC’s mid-season drama "Crisis." The show might have just been dropped by the network but the youngest Scott brother is still living a pretty awesome life. The girl had no problem stripping down and taking what she wanted -– mainly all the boys at Tree Hill High -– and she provided the show with some much needed sass whenever possible.
He listens to Haim on the reg, loves watching Scandal -– hopefully while drinking a glass of red wine -– and doesn’t mind breaking it down in a "Star Wars" costume anytime the "Harlem Shake" comes on, as this video proves. She started her own fashion line, survived being assaulted in a parking lot, dealt with terrible parents and eventually found true love with a man she didn’t meet in high school (shocking! Now Like her character on the show, Bush fell in love quickly.
She dated a few of her co-stars and was even married to Chad Michael Murray for a time before the two called it quits.
It's hard to believe that "One Tree Hill" first premiered over a decade ago.
If you had the distinct pleasure of entering your pre-teenage years in the 2000s, you're likely familiar with the CW soap that featured a group of popular kids trying to break free from the stress of high school and small town life.
The show gave us so much: teen marriages, unrealistic expectations, a hard look at the cruel world that is high school sports and a Gavin De Graw theme song that perfectly described every angst-ridden teenager's journey to adulthood.
Then Bethany Joy Lenz played responsible and pragmatic Haley on "One Tree Hill." The best friend of Lucas Scott and future love interest of his half brother Nathan, Haley found herself in the middle of more than a few love triangles during the show.
She eventually got married -– while still in high school -– had two children and by the series finale was happily balancing her budding music career with family life in Tree Hill.
Now After the show wrapped, Lenz took a page from her character’s book, got married and had a daughter named Maria Rose before eventually divorcing her husband in 2012.
After touring with artists like Michelle Branch and Gavin De Graw, Lenz went back to acting, booking a guest role on "Dexter" –- she had the misfortune of being Dexter’s neighbor during the eighth season of the show.
She’s still writing music and loves tweeting about all of the charities she’s involved with.
