Kelly Rohrbach's Pantsless Pic, Justin Bieber's Calvin Klein Campaign, and Much, Much More

Here's what all the buzz is about:

• The other day on Instagram, Sports Illustrated model Kelly Rohrbach (who also stars in the upcoming "Baywatch" film) posted a pantsless picture of herself from an unnamed magazine spread (above). She also neglected to mention how she misplaced her pants, so we'll simply have to fill in the gaps for ourselves: We're thinking wolves!

• Speaking of lovely swimsuit sirens, we recently had the pleasure of interviewing Mara Teigen after her auditions for the Sports Illustrated Swimsuit Issue. Watch the video below to learn a bit about the casting process, then modeling decidedly less than Kelly up there.

• According to sources for Billboard, Rihanna is planning to surprise fans by releasing her new album "Anti" sometime this week. So at long last, listeners will finally learn whether "B**** Better Have My Money" was just a one-off musical theme, or if it's part of a larger, overarching concept album about the many b****es who never seem to have Rihanna's money.

• Calvin Klein has debuted a new ad campaign featuring Justin Bieber, Kendall Jenner, and a slew of other young celebrities modeling the brand's underwear (see Bieber's ad below). The running theme of the ads seems to be "I [blank] in #MyCalvins," so it's only a matter of time before an especially clever graffiti artist spray-paints the word "peed" on all the CK billboards in SoHo.

• Award-winning recording artist John Legend revealed to Us Weekly that he's writing a song for his unborn child. Unfortunately, he couldn't provide more details about the track, but if it's half as sweet and beautiful as the one he wrote for wife Chrissy Teigen ("All of Me"), it's going to make us all feel like lazy, horrible parents by comparison.

• In honor of Warner Bros. upcoming "Superman v. Batman" film, Empire magazine has debuted two new covers for their March issue: one featuring an exclusive photo of Ben Affleck in his complete Batman get-up, and the other featuring a photo of Henry Cavill as Superman after ingesting some severely undercooked poultry:

• As confirmed by Us Weekly, "Sicario" actress Emily Blunt is expecting another baby with "13 Hours" actor John Krasinski. This will their second child (the two welcomed a daughter named Hazel in 2014), but perhaps only the first that won't immediately recognize its dad as "that guy from 'The Office.'"

• Character actor Abe Vigoda died peacefully in his sleep on Tuesday morning at the age of 94. He'll be remembered fondly for his roles of Sal Tessio in "The Godfather" and Phil Fish on TV's "Barney Miller," but also for lending some much-needed credibility to "Good Burger" and delivering the film's most memorable line:

• And finally, according to Pitchfork, Kanye West will debut his new album (which he's calling "Waves" now) during a listening party at Madison Square Garden that will also be screened in theaters worldwide. (At the moment, he has no plans to forcibly beam his new tracks directly into our brains, but be warned: He will if he ever masters the technology.)
