Beyoncé has been very protective of Blue Ivy since her birth, but she is showing off her bundle of joy in her new HBO documentary Beyoncé: Life Is But a Dream. The adorable one-year-old daughter of Bey and Jay-Z steals the screen as her proud mama holds her up in a still from the film.

See more of baby Blue and her mother when the film premieres tomorrow at 9 p.m. on HBO.
