The 27-year-old Big C actress was just one of many celebs to check out the screening, which was hosted by 50 Cent and Harvey Weinstein.
Although Gab loved the movie, she told everyone to make sure not to spoil the fun for others.
“Scream 4….Worth it! I loved it! Maybe you will too but don’t spoil the ending for anyone! That’s just mean!” Gabby dished on her official Facebook page.
