The "Blurred Lines" singer revealed to E! News' Alicia Quarles at the grand opening of the Express store in Times Square that he and the actress are "both very happy."
Thicke, who was extremely open about his desire to save his relationship during several concerts on his North American tour, also told us that he couldn't help but wear his heart on his sleeve after the couple announced that they were separating.
"I wasn't sharing anything except what I was going through at that very second. So for me, as an entertainer and a songwriter, it's important for the music to be honest," he shared.
"I just try to be as honest as I can."
The two have been seen in public together since the news of their split went public, and have both been spending quality time with their son, Julian.
"He just spent a week with me on tour," Thicke said with a big smile.
And what does the singer, who melts the hearts of women everywhere, find sexiest in a woman?
"Sense of humor," he admitted. "There's nothing that's more important than being able to laugh with somebody, because we all have tough times, but if you can laugh through life, you can get through anything."
