Randi Jayne Zuckerberg, the nerd chanteuse and sister of Facebook CEO Mark, visited the fair island of Manhattan last week and frankly, we'll never be the same. Zuckerberg — sorry boys, she's planning to wed in May — came to town with her mother. Notorious notoriety-possessor Julia Allison roped Zuckerberg into a meal — and one of her lip-sync videos. We haven't seen the video yet, but we're hoping wantrepreneur Allison was smart enough to hand over creative control to the vastly more talented Zuckerberg. She's excellent at show tunes. Stills from the shoot are below.
