Alessandra Ambrosio's Rio Vacation, Elsa Hosk's Behind-the-Scenes Swim Special, and Much, Much More

Here's what's on our radar:

• This past Tuesday on Instagram, Victoria's Secret supermodel Alessandra Ambrosio posted a bikini pic from her vacation in Rio de Janiero. It's stunning, for sure, but it's got us wondering: Do any of these girls ever take a vacation from modeling skimpy clothing? You'd think one of them would head to Finland and take some selfies in a parka or something.

• Speaking of Victoria's Secret models who look great in a bikini, we recently got some behind-the-scenes info on the VS Swim Special that aired earlier this year — from none other than Elsa Hosk herself. To see what Hosk had to say, as well as some clips from the Swim Special, be sure to watch our exclusive interview above.

• Leonardo DiCaprio has reportedly become an investor in a start-up mattress company called Casper. He joins Adam Levine, Toby Maguire and music mogul Scooter Braun as fellow backers, and also as people we can generally trust regarding the quality, durability and prowess of mattresses.

• In an interview with Howard Stern on SiriusXM satellite radio, "Magic Mike XXL" star Channing Tatum revealed he "f***ing hated" his own film "G.I. Joe," and said he only did it because he was contractually obligated. However, he neglected to make any valid excuses for "Step Up 2: The Streets."

• Former professional wrestler "Nature Boy" Buddy Landel died this past Sunday due to complications following a car accident near his home in Virginia. Landel is not to be confused with "Nature Boy" Ric Flair, although you wouldn't be faulted for thinking that, especially after their "Battle of the Nature Boys" in 1990:

• English actor Tom Holland has been chosen to play Peter Parker in Sony's next big-screen "Spider-Man" reboot. At just 19, Holland doesn't have many film credits to his name — let alone credits that Americans would be familiar with — but that shouldn't be a problem for most audiences. We don't care about his face; we're all just waiting for the part where he puts on a mask and kicks a goblin-man in the head.

• In an interview with Hello! magazine, Lindsay Lohan claimed that she "can definitely see [her]self settling in London permanently." And while Lindsay's state-side detractors might be thrilled at that prospect, such a thing would certainly be detrimental to the U.S. economy: Just think of all the highway patrol officers and and Los Angeles County attorneys she'd put out of work!

• Dick Van Patten, probably best known for playing Tom Bradford on "Eight is Enough" and his numerous appearances on "The Love Boat," has died of diabetic complications at a hospital in Santa Monica, California. He was 86.

• The people behind the 2005 movie "Mr. and Mrs. Smith" — which starred Brad Pitt and Angelina Jolie as secret agents assigned to kill each other — are currently working on a reality-competition TV series based on the film. Further details are slim, but we can't imagine the contestants will be goaded into actually killing their spouses. Besides, that was already the plot of "Temptation Island."

• Earlier this week on Instagram, Tallulah Willis shared a photo of mom Demi Moore, 52, wearing a string bikini by the pool (below). Tallulah and her sister Scout were also in the pic, but Tallulah wisely focused the attention on her mother in the caption, hashtagging the post with "#mymomsbodtho" and summing up what roughly 100 percent of her followers were thinking.

• In an interview with GQ, Jaden Smith finally explained the all-white Batman outfit he wore to Kim and Kanye's wedding, as well as his own prom: "I felt as though I needed to protect everyone there and needed to have the proper gear to do so," he said, which, in retrospect, doesn't really explain a freakin' thing. Great reporting, GQ!

• And finally, 50 Cent brought actor Mark Wahlberg on stage at a New Kids on the Block concert in Madison Square Garden on Monday (it makes more sense after seeing the video below). But despite the DJ queueing up "Good Vibrations" from his Marky Mark days, Wahlberg didn't do much more than greet his brother Donny and the rest of his NKOTB bandmates. He might be above his rapping days anyway, especially now that he's moved on to making jokes about sperm banks and plumbers' butt.
