Celtic earned its 12th-straight Scottish 0 defeat of St. Mirren at St. Mirren Park.
The Hoops did not break through until the 71st minute when James Forrest claimed his sixth goal of the campaign. Scott Brown tacked on a second goal two minutes from time to wrap up three points for the visitors.
Celtic has not dropped points in the Scottish league since Oct. 29 when it was held to a scoreless draw against Hibernian. It has not lost a league game since its 4-2 Old Firm drubbing to Rangers on Sept. 18.
The win also extends Celtic's lead at the top of the table to four points after Rangers were held to a 1-1 home draw with Aberdeen. The Hoops set the pace with 59 points on the year.
St. Mirren, meanwhile, suffers its third-straight defeat in league play and remains in the thick of the relegation playoff picture. The Paisley club is tied with Aberdeen on 26 points apiece.
