The 27-year-old Arrow star took to Instagram where he also shared a photo with her.
“Happy Birthday to the best friend a person could ask for @allymaki,” Colton wrote. “If I could write a book on how much this beautiful person has helped me over the last 9 yrs…we’d have a best seller on our hands.”
He continued, “She’s always been such a light in my life & makes me laugh more now than she did when we met in an audition room for a role she booked and I didn’t ha. I never would’ve gotten through this year without her being there for me & making sure I was sane. I love you so much Al. Thanks for always bein you & cheers to many more Miami bdays :) #HappyBdayAlly”
Happy birthday, Ally!
