On Saturday night, Hollywood's biggest stars gathered in Washington, D.C. for the 98th annual White House Correspondents' Dinner. Jimmy Kimmel emcee'd the event, which served almost as a "roast" of sorts -- Jimmy and President Obama took to the stage to make fun of celebs including Lindsay Lohan and Kim Kardashian (both of whom were in attendance)!

Also at the party? Pregnant actresses Reese Witherspoon and Anna Paquin, Harry Potter star Daniel Radcliffe, the always-dapper George Clooney, and many, many more!

It seems like everybody wants Jennifer Aniston to get pregnant, have a baby and live happily ever after, right? Otherwise, why would rumor after rumor be on the cover of every tabloid magazine at the grocery store saying she’s expecting?

Well, Jen put those rumors to rest in an interview for the latest issue of GQ -- but easily denied them by taking off her shirt for the photo shoot with Wanderlust co-star Paul Rudd. Her abs can deflect any pregnancy rumor, that's for sure...

Take a look at all the pics!

The cast of How Do You Know hit the red carpet at the Los Angeles premiere of their highly-anticipated romantic comedy in Westwood, California on Monday night, December 13th.  Reese Witherspoon, Paul Rudd, Owen Wilson and Jack Nicholson talked all about love and laughter at the soiree. 

Hollywire's own Katie Krause was front and center on the red carpet talking to all of the hottest stars from the upcoming flick.
