The 30-year-old actress, who is engaged to the singer-actor, said that communication is one of the most important aspects of any union, reported Contactmusic.
"What do I value in a partner? Communication. Men and women speak a completely different language, so if you can communicate easily on a daily basis, that's pretty impressive.
I have that with Justin," Biel said. Despite being happy with Timberlake, the actress does have regret the fact that she did not finish college. "I wish I had graduated college.
I regret not spending time with my peer group, because at the time I had been working with adults for so long. I was, like, 20, at the time, and chose to focus on acting," she added.
