THE “Saturday Night Live” cast took a break from rehearsals this week to see the Knicks play. Pete Davidson brought Chance the Rapper (above), who’s hosting Saturday. Other “SNL” regulars to Madison Square Garden on Monday included Michael Che and Leslie Jones — who asked former Knicks star Latrell Sprewell for a selfie. The “SNL” workweek begins Monday, with staff pitching ideas to Lorne Michaels. Also in the MSG crowd: Chris Rock, Mariska Hargitay and Henrik Lundqvist.
