Jennifer Lopez's Low-Cut LACMA Look and Del Frisco's Grille's Mayan Manhattan

Here's what everybody's going on about:

Us Weekly has determined the five hottest looks from Saturday night's LACMA Art and Film Gala in Los Angeles, among them Amy Adams, Selena Gomez and Jennifer Lopez (below), or pretty much anybody who turned up showing major cleave.

Sick of the same old cocktail? Maybe it's time to switch things up with a Manhattan that's not really a Manhattan at all. Treat yourself to a Mayan Manhattan after work tonight, just like the one they make at NYC's Del Frisco's Grille. Watch the video above to see how they mix things up.

Kendall Jenner and Cara Delevingne went as Mario and Luigi to a Halloween party in Hollywood on Friday night (below), albeit a much more attractive Mario and Luigi, without paunchy beer bellies, stumpy cartoon legs, or knowledge of the plumbing arts.

Seth Rogen will take a break from playing heavyset slackers to portray a heavyset technology pioneer in the upcoming Steve Jobs biopic starring Christian Bale, where he's reportedly signed on to play Apple co-founder Steve Wozniak.

Lindsay Lohan and her brother Michael are being sued for $60 million by a former business associate who claims they stole his contacts and mobile app idea. In even more shocking news, who the heck knew Lohan had a brother? She really kept that one a secret, didn't she?

"Here Comes Honey Boo Boo" patriarch Sugar Bear reportedly lost consciousness passed out at his ex-lady Mama June's house on Sunday. The EMTs determined the cause to be high blood pressure, although the fact that the mother of his child is reportedly dating a man who was convicted of child molestation probably didn't help.

"Rizzoli and Isles" star Angie Harmon and her husband, former NFL cornerback Jason Sehorn, are "amicably separating" after 13 years of marriage. We're not sure of the reason for the split, but we're pretty sure he was sick of people mistakenly calling him "Isles."

Heidi Klum dressed as a psychedelic humanoid butterfly woman for her annual Halloween party (below), no doubt giving her guests terrible acid flashbacks of their old college years. Especially those few years when they roomed with an entomology major.

Apparently unaware that she's always wearing some type of ridiculous Halloween costume, Lady Gaga nabbed a tablecloth from a Parisian restaurant to fashion herself a makeshift ghost costume for the ride back to her hotel.

After reportedly being kicked off Instagram six months ago (presumably for her risque uploads), Rihanna somehow returned to the social media site this past Sunday. So expect none of the virtual nudity that made her account so popular in the first place. For now, she's sticking to sexy "Teenage Mutant Ninja Turtles" costumes:

And finally, Taylor Swift announced her "1989" world tour on Monday morning's episode of "Good Morning America." You can learn how to purchase pre-sale tickets here, but you're going to have to wait until 2015 before you can buy a "Taylor Swift 1989 World Tour" t-shirt that will seriously confuse the heck out of anybody around you.
