Entertainment buzz: Facebook's top 10 moments of the week

A little baby got a big dose of Internet fame this week with a little help from Katy Perry, and moviegoers packed theaters for an intergalactic Marvel adventure.

New music from Beyonce that addressed a certain elevator fight also got attention, as did harsh words from Jon Voight to other Hollywood stars about Israel and Gaza.

Facebook has tallied the top 10 buzziest stories in entertainment this week, and all of those topics made the most-talked-about list. What had you talking? See what you missed in this exclusive list on CBSNews.com.

3. Marvel's "Guardians of the Galaxy" rockets to the top of the box office

We bet even Groot is pleased (though all he'll say about it is, "I am Groot").
