Bill Murray Escorts Lady Gaga to Roseland Ballroom & “The Late Show with David Letterman”
The “Groundhog Day” actor addressed the crowd outside with a megaphone as the “Just Dance” songstress paraded around in her crazy green wig.
Gaga and Murray also paid a visit to “The Late Show with David Letterman” for a special selfie moment and her first ever performance on the program.
Prior to the photo, Bill asked Dave, "I haven't done that yet, is there any way? I've got stuff to do later...."
Gaga added, "Hey, what are you guys doing tonight, 'cause I have a show across the street and if you want to come over, I’ll bring you. You can see the performance. I’ll bring the audience...You can come over and I’ll sing you some songs."
