Celtic beat Rangers 4-0 at Hampden on Sunday to set up a Scottish Cup final meeting with Motherwell on Saturday May 19.
First-half goals from Tom Rogic and Callum McGregor had Brendan Rodgers' side in control at the interval and Moussa Dembele and Olivier Ntcham both converted second-half penalties after Ibrox defender Ross McCrorie had been sent off.
Celtic remain on course for a historic double Treble and have a chance to clinch the Ladbrokes Premiership title against Hibernian on Saturday.
