New York Giants co-owner Steve Tisch and movie moguls Harvey and Bob Weinstein are throwing a Manhattan celebrity pep rally to cheer on the team as it prepares for the Super Bowl.

They are hosting a giant party at power lunch palace and Midtown media mecca Michael’s on Wednesday.

While the team will already be in Indianapolis, they’ve lined up a roster of co-hosts, including Matt Lauer, “SNL’s” Lorne Michaels, Brian Williams, John McEnroe, Sports Illustrated’s Terry McDonell and Dick Ebersol.
