Harris and Burtka first spent time hanging out with each other platonically.
"We began hanging out with other people, and we had a lunch or so, but nothing romantic," Burtka wrote for Out. "I thought he was adorable, though, with these amazing blue eyes that are just hypnotizing to me."
Burtka eventually broke up with his long-distance boyfriend, and a week later, he and Harris went to see a movie as their first date. After that, the two became nearly inseparable.
"We started hanging out every single night, and after three months, it was just nonstop," Burtka added. "We talk on the phone at least eight times a day and text at least 25 times a day."
