A year later, the charges against him were dismissed.
Since the show ended, he's popped up in the films Eloise, Mountain Men, and Rules Don't Apply.
The stars of the juicy hit have all experienced ups and downs in the years since, with bumpy careers and, at times, even bumpier personal lives.
This summer, he had a guest spot on the Hulu series Casual — where he bared his backside for the camera.
He also starred in the short-lived show Blood & Oil.
In February of this year, he married musician and doula Domino Kirke, who is the sister of actresses Jemima and Lola. Like his co-stars, Chace, 32, took on a few extra gigs while Gossip Girl filmed, including voice work on Family Guy, the starring role in the movie Twelve, and a spot playing Anna Kendrick's baby daddy in What to Expect When You're Expecting.
He also found himself in a bit of hot water, getting arrest for marijuana possession in Texas.
Her singles included Somebody to Love, our Love's a Drug, and vocals for Cobra Starship's Good Girls Go Bad.
She finally released her own album, Heartstrings, in 2014, and went on tour the following year.
In addition to steady work on the silver screen, Blake's also raking in big bucks with sponsorship deals.
She's been the face of Chanel and Gucci Premiere, and is currently a brand ambassador for L'Oréal Paris. In 2014, Blake launched an artisan lifestyle website called Preserve which flopped spectacularly and was shuttered the next year.
