Amy Grant on how her song 'Baby Baby' has come full circle 30 years later

Amy Grant has just released a 30th anniversary edition of her 1991 album "Heart In Motion," which produced multiple smash hits, sold five million copies and was nominated for the album of the year Grammy.

Grant, in a new interview with ABC Audio, said she has nothing but good memories of the album, and her time as a chart-topping pop star.

"Everything about that project is just ... full of joy and kindness and it's been so much fun to revisit," she gushed. "Here's the crazy thing about this record: It was totally out of print! It was fun to go back and make it available in all formats -- except cassette and eight track!"

"Heart In Motion" featured the songs "That's What Love Is For," "Good For Me," "Every Heartbeat," "I Will Remember You" and, of course, the No. 1 hit "Baby Baby." Grant said that song in particular has become a full-circle moment for her.

"'Baby Baby' was inspired by [my daughter] Millie," she recalled. "I was pregnant with her when I was writing a lot of that record ... she was 1 when the record came out, and then we toured and she was learning to walk."

And on the Fourth of July, Grant revealed: "[Millie] told the whole family she is expecting a baby girl. So 30 years later, she's now the age I was when I made that record. You just can't script that!"

Another thing that makes her realize just how long it's been since "Heart In Motion" came out is where she recently unexpectedly encountered Jme Stein, her co-star in the "Baby Baby" and "Good For Me" videos.

"I saw him on a Viagra commercial," Amy laughed. "And I went, 'My, how time flies!'"
