The three are reuniting with their original music producer, Glen Ballard,on the Christmas-themed album.
Ballard co-wrote Michael Jackson's hit single "Man in the Mirror" and produced Alanis Morissette's "Jagged Little Pill" album. He was also the main producer behind Wilson Phillips' self-titled 1990 debut album, which sold more than 10 million copies worldwide.
"Reuniting Wilson Phillips with the multitalented pop producer and songwriter Glen Ballard on an album featuring Christmas favorites and newly written songs is certain to become a holiday classic," Alex Miller, senior vice president and general manager of Sony Masterworks, said in a statement.
The trio is also expected to announce tour dates in the near future, the act's record label said.
