For his latest album, On PurposeClint Black reunited in the studio with his wife, actress Lisa Hartman Black, for a new duet, "You Still Get to Me." The song was written by the country music hitmaker and Victoria Shaw, and Black says that he was thrilled to have his wife working with him once again.

"As soon as she opens her mouth and starts singing, it does something to me," Black reveals to People"I know the wonderful person behind that voice, so it becomes a great big joy for me."

Black first sang with his wife on the 1999 hit "When I Say I Do," from his D'Electrified album -- although she almost didn't appear on the chart-topping single.

"It was four days from the deadline when I guilted her into it," he recalls to Rolling Stone Country. "Then she said she wasn't going on The Tonight Show, but she did that. She said, 'I'm not doing it live!' But she did that, too."

The pair, who wed in 1991, are still as in love as ever.

"The attraction is still there," Black maintains. "She's even more beautiful today, especially knowing what she is on the inside. She cares and loves bigger and better than I could, so I've been elevated to do a bigger and better job at loving and being kind and considerate.

"We started out in love and committed, and then we did all of the things we thought would support that commitment, communication being huge," he adds. "You have to grow together, or you will grow apart."

On Purpose is indicative of where Black is in both his personal and professional life.

“It represents my attitude towards life, in that it’s never easy to ‘go your own way,’ but the rewards are greater when you follow your heart,” Black explains. “I know that’s what my fans expect from me, and I hope that they hear that in the songs on this album.”

On Purpose is available for purchase on iTunes and Amazon.
