Celtic took another huge step towards reclaiming the SPL title after a 2-0 win over Dunfermline opened up a 20-point lead at the top.
Sixteen straight league wins have seen the Bhoys take firm command of the title race, even without Rangers' recent points penalty, and a superb Charlie Mulgrew strike and James Forrest's goal clinched the Parkhead points.
The Hoops have been red-hot in front of goal and Ki Sung Yueng's early effort tested Chris Smith, while Gary Hooper's drive was pushed wide by the Pars keeper.
But Smith was powerless to prevent Celtic's stunning opener as Mulgrew's fierce 30-yard drive flew into the top corner (31), and Kris Commons' shot nearly added a second before the break.
The slipshod Pars defence should have been breached again in the second period as Anthony Stokes shot wide after racing clear, but Celtic were given a scare when Ryan Thomson's shot was blocked on the line by Emilio Izaguirre.
Celtic soon regained control and Forrest added a killer second from close range after he was teed up by Hooper, while Commons fired over late on.
