Ireland Baldwin's Schoolgirl Outfit, Christie Brinkley's New Beau, and Much, Much More

Here's what people are talking about:

• Despite already looking like a sexy Ireland Baldwin, Ireland Baldwin dressed up as a sexy Britney Spears (above) for Galore magazine's "Generation Bombshell" party. As you can see, she's chosen to replicate a look from Spears' earlier years, as opposed to Spears' later years, after she grew out her pork-chop sideburns and pompadour and started dressing in studded white jumpsuits.

• Also, as she revealed online on Tuesday, Ireland Baldwin's upper arm is now tattooed with a simple drawing of David Bowie's "Aladdin Sane" album (below), just like the kind you used to doodle in your notebook during 11th-grade history class. At this time, it's unknown whether she also got your pot-leaf drawings or "AC/DC RULEZ" sentiments inked elsewhere on her body.

• Ageless supermodel Christie Brinkley and roots-rocker John Mellencamp were spotted on a dinner date earlier this week in NYC. Could they be a new couple? Maybe, but we doubt it. For starters, we just described her as an ageless supermodel, and him as a "roots rocker" because Wikipedia had to remind us what to call his brand of inoffensive rock.

• Disney has released the first trailer for its live-action adaptation of "The Jungle Book," which looks about a thousand times grittier that the original 1967 animated film (below). So in this version, we probably shouldn't expect a memorable dance sequence between Mowgli and Baloo, but instead a harrowing scene where Shere Khan viciously mauls a young human boy:

• Mark Zuckerberg announced on Tuesday that Facebook will soon be adding a "dislike" button alongside its "like" button, but claims they're only doing it to give users the ability to empathize with friends who are going through rough times. And we're sure that's exactly how it will be used, right after we dislike our friend Stacy's latest picture of her stupid cat.

• On Tuesday, the first trailer for the next installment of the "Divergent" series — subtitled "Allegiant" — made its debut online (below). It's only a few moments long, but it confirms that this latest sequel will continue the series' tradition of having Shailene Woodley and Theo James shoot at things with guns, and also its tradition of having a vaguely important-sounding though ultimately dumb subtitle.

• According to E! Online, Justin Timberlake will be lending his voice to an upcoming animated film based on those little Troll dolls that gained popularity in the '90s, perhaps because Timberlake also has experience as part of a popular '90s craze that imploded and had generally terrible hair.

• Mariah Carey has replaced Kate Upton as the chesty female warrior in the latest (and soon to be ubiquitous) "Game of War" ad, which also heavily features Mariah's song "Hero." You can watch it below if you like, but why should you? If history is any indication, you'll see if four times on your mobile phone in the next hour, then another dozen times on your TV, your iPad, your fridge and your toaster before hitting the hay.

• And finally, former "Game of Thrones" actor Richard Madden called Cara Delevingne "unprofessional" for giving an awkward interview with "Good Day Sacramento" earlier this summer, but Delevingne has already fired back by tweeting "I don't know who you are" directly at Madden. It's a respectable comeback, but c'mon, Cara — everybody watched at least the first season of "Game of Thrones."
