The 30-year-old Scotland international has invited the former Celtic duo to the club’s Scottish Premiership title party next weekend.
The Bhoys have won the Scottish top-flight title for the fifth season in a row and are on a high at the moment.
Provan, who played for Celtic in the 1970s and 1980s, was recently critical of Brown.
Writing in The Scottish Sun, the former Scotland international claimed that the new manager of the Bhoys should be looking for a new leader in the dressing room.
The ex-Kilmarnock man also wrote that he would remember Brown as “a poor man’s Murdo MacLeod”.
Former Celtic striker Walker has been critical of the Hoops throughout the season, and this is not the first time that Brown has hit back at him.
Earlier this month, the former Hibernian star suggested to The Glasgow Evening Times that Walker is jealous of Celtic’s current success in the Scottish Premiership.
