Oprah will be sitting down with Beyonce just before her self-directed documentary, "Life Is But A Dream," premieres on HBO.  And it looks like she's looking for Queen B to get personal on her couch as well. 

The last time Oprah sat down with Beyonce was back in 2008, shortly after her marriage to Jay-Z.  Beyoncé wasn't nearly as open about her personal life then.  But she's since brought her daughter Blue Ivy into the world and now she's gearing up for a huge world tour. 

Beyoncé's interview with Oprah will air on OWN this Saturday, starting at 8:00 p.m. Eastern.
