Here's a peek at what's going on:

Miley Cyrus has teamed up with The Flaming Lips and one half of MGMT to record a cover of "Lucy In the Sky With Diamonds" by The Beatles, during which they were appropriately stoned off their faces.

"Lovelace" actress Amanda Seyfried told W magazine that she loves filming sex scenes ("I’m not going to pretend it’s not fun"), and especially her make-out scenes with Megan Fox when they co-starred in "Jennifer's Body" (“We kissed really well together").

Speaking of Seyfried, she also sneaked a Swiss Army knife aboard a plane (unintentionally) and then alerted the TSA afterward, through Twitter. It's hard to tell her tone through the tweet, but it sounds a little like she's calling them out for being crappy at their jobs.

Historian Michael Beschloss found and shared one of Jacqueline Kennedy's selfies, which she snapped 60 years ago while sister-in-law Ethel and husband John crowded 'round.

"Motley Crue" bassist Nikki Six, 55, just got hitched to a 28-year-old model named Courtney Bingham. That would mean she was only 1 or 2 years old the first time he was declared legally dead.

Actor and "Seinfeld" nemesis Wayne Knight (Newman!) was not killed in a tractor-trailer incident, as the internet may have led you to believe. He's in fine health, and presumably watching us kiss in a darkened theater during "Schindler's List."

Justin Bieber went and got himself a forearm tattoo in the style of Banksy's "Balloon Girl" graffiti, but future police will simply recognize it as yet another identifying characteristic.

Miley Cyrus, too, got a new tattoo: a "sad kitty" emoticon face on the inside of her lower lip.

Comedian and frequent "Tonight Show" guest David Brenner passed away on Saturday at his home in New York City. He was 78.

Demi Lovato is mad at Lady Gaga for "glamorizing eat [sic] disorders." And by "glamorizing eat disorders" she evidently meant "allowing a performance artist to vomit green milk on your torso." Because they're clearly one and the same thing, according to Lovato.

On Monday morning's "Today" show, host Savannah Guthrie revealed that she's both married and pregnant. (Beat that, Matt Lauer.)

For Purim, Madonna dressed up as the Khaleesi from "Game of Thrones" and uploaded the photos to Facebook.

Kate Middleton got to celebrate St. Patrick's Day in Aldershot, where she handed out shamrocks to the Irish guards.

Despite the rumors, Angelina Jolie told Entertainment Weekly that she never really considered directing "Fifty Shades of Grey." Angelina Jolie has higher standards than that, says Angelina Jolie.

Jennifer Hudson will no longer be a spokesperson for Weight Watchers. Because they can watch their own weight, gosh darnit.

In news that will shock probably no one, "Labor Day" actor Josh Brolin told UK's The Guardian that he's tried heroin in the past. "I never died from it, which is a good thing," he added, just to clarify for anybody who thought otherwise.

Brolin's "Labor Day" co-star Kate Winslet will be honored with a star on the Hollywood Walk of Fame today. That's the Walk of Fame located in Hollywood, just to clarify for anybody who thought otherwise.

Cher recently revealed that designer Bob Mackie won't be outfitting her for her final concert tour. She'll just have to find someone else to sew her a butt-less leather ensemble.

Kendall Jenner is continuing on her Kardashian-like trajectory, Instagramming pictures of herself clad in little more than Calvin Klein underwear.

And finally, Prince Harry's girlfriend Cressida Bonas has reportedly told friends that she doesn't want to get married yet. "Too bad," says the entire royal-watching world.
