Kristin Cavallari's Workout Selfie and Kristin McGee's Ab-Toning Exercises

Here's what everybody's gabbing about:

Reality star, fashionista and all-around lifestyle specialist Kristin Cavallari flaunted her amazing post-baby body on Instagram this Sunday (below), apparently because having a very vague job description allows for lots of opportunities to work out.

Now that you've seen Kristin Cavallari's unbelievable abs, it's time to get some for yourself. In the video above, celebrity yoga and Pilates instructor Kristin McGee shares her top three exercises for a flat tummy. Click play and get crunchin' like a pro (or a very fit reality TV star).

After two years of being engaged, Nicole "Snooki" Polizzi and Jionni LaValle tied the knot in a "Gatsby-themed" wedding on Saturday in New Jersey. We're not sure exactly which wedding elements were "Gatsby-themed," but hopefully nobody was murdered on account of their own hubris.

The first trailer for "Star Wars: The Force Awakens" debuted on Friday (below), and some fans are already objecting to its inclusion of a black stormtrooper (for both racist and continuity-based reasons). But since these are the same people who didn't have a problem with the original films and their depiction of a humanoid alien race speaking perfect English (sometimes with British accents), let's stop paying them any mind.

A few days ago, PEOPLE magazine's website accidentally ran an obituary for 97-year-old "Spartacus" actor Kirk Douglas, who is still very much alive. Hopefully, they got it down before Douglas himself saw it, became overwhelmed with a surreal sense of mortality, and keeled over on the spot. That would've been quite the catch-22.

According to sources for Page Six, Scarlett Johansson and Romain Dauriac got married in a secret ceremony shortly after the birth of their daughter in September. This news probably comes as a devastating shock to any ScarJo admirers out there, but please, don't fret. You never really had a shot with her anyway.

A new preview for the "Breaking Bad" prequel "Better Call Saul" debuted on AMC this Sunday (below), but surprisingly, it's looks like it's not a gritty origin story of how Saul Goodman became a loudmouth jerk. As shown in this clip, he was like that all along!

Actor and sporadic-pugilist Mickey Rourke ("The Wrestler," "The Pope of Greenwich Village") participated in his first boxing match in 20 years on Friday in Moscow, but now it's being reported that his adversary was paid to take a dive. This news comes as a huge surprise to anyone who somehow believes a 62-year-old can beat up a 29-year-old, and absolutely no one else.

Speaking of actors and boxing, Jake Gyllenhaal packed on a bunch of muscle for his role as a boxer in the upcoming film "Southpaw" (see pic below), which is a far cry from that skinny, scraggly "Nightcrawler" Jake Gyllenhaal we saw earlier this year, whom you might have knocked over with a forceful sneeze.

David Beckham and his son Brooklyn were reportedly involved in a violent car collision just outside of London on Saturday. But luckily, the airbags deployed, and David and Brooklyn's handsome, handsome faces suffered no damage or disfigurement.

As evidenced by the recent photos she's been posting to her Instagram account, Shania Twain has been writing and recording music for an all-new album. In one of them, she's even got two Mac laptops on her desk (below), which is the universal sign of someone who means serious business.

And finally, "The Hanging Tree," a song sung by Jennifer Lawrence in the new "Hunger Games" film, is already racing up the U.K. and Australian singles charts, and it's poised to do the same in the U.S. It just goes to show that all countries — no matter what our differences — celebrate songs about murder, especially when those songs complement films about child murder.
