2011 was the year of the celebrity feud!

It seemed that everyone was bashing the Kardashians! After Kim's extravagant marriage to Kris Humphries that she ended after just 72 days, the reality-TV first family really fell from grace.

Michelle Obama was first up, sharing that Barack does not like their two young daughters watching the Kardashian shows. A slew of celebrities followed suit, with Daniel Craig, Cher, Reese Witherspoon and Chelsea Handler amongst the stars slamming the Kardashian's.

January Jones: A-list name, B-list (as in “bad”) attitude?

Seems to be the case, at least according to those who've crossed paths with the Mad Men beauty.

The latest to go public with tales of Jones' surly reputation is Jared Gilmore, the 11-year-old child actor who left Mad Men for a role on ABC’s Once Upon a Time.

Asked what advice he'd give his replacement, he told TV Guide that new faces on the set of the AMC hit should walk on eggshells around the 33-year-old actress, who played his mother on the show.

The Wolfpack is back and how! The Hangover Part 2, with Bradley Cooper, Zach Galifianakis and Ed Helms, scored the biggest opening of an R-rated comedy ever.  Its box office estimate for the five-day Memorial Day weekend is $137 million.

For movie-goers with kids, Kung Fu Panda 2 proved a popular choice.  It came in second, with an estimated $68 million take for the holiday weekend.

In the segment, Aniston came out to a pathetic version of the Friends theme, and seemed awkward and disoriented by the vibe in the room. Galifianakis introduced Tila to Aniston as the star of a reality dating show.
