This weekend the ever-powerful Beyonce debuts her first documentary, “Life Is but a Dream.” Fans are hoping to get an inside glimpse of what it’s really like to be Bey. I’ll be tuning in to HBO this Saturday at 9 p.m. for sure. In the meantime, click through the gallery to see Beyonce’s Tumblr pics from the documentary’s premiere— Oprah included! xoxo, Whit
