Dax Shepard, Kristen Bell & Justin Bieber
The married actors compared residing next to the "Sorry" crooner to "living in Lebanon," with Kristen adding, "In his defense, I will say we don't know the exact house the music is coming from. We just know since he moved in, the music has been blaring."
Kendall Jenner & Jimmy Kimmel
The late-night host might be looking forward to catching up with his neighbor across the street over dinner, but not everybody welcomed the supermodel when she moved in. "Our neighbors were up in arms when you moved onto the block. There was a whole thing with emails that went on," he joked to Jenner. "It was bad!"
Meryl Streep & Gwyneth Paltrow
Who better than the Goop goddess herself to save the day? But as it turns out, there is something better than Gwyneth... her oven! The lifestyle guru wasn't in New York City for the 2014 Thanksgiving holiday, so she let Meryl borrow her kitchen when a cooking crisis struck.
Miley Cyrus & Steve Carell
The stars' neighborly relations haven't always been the most friendly, with the pop singer telling Rolling Stone in 2013, "He always gives me the stank-eye because I drive so fast." Yikes!
Kim Kardashian, Kanye West & Kathy Griffin
The comedienne moved right next door to the famous couple's Bel Air mansion earlier this year. Griffin told People magazine, "One time [Kris Jenner] came over, and she opened the window and started yelling at Kim and Kanye and I said, 'Stop it! You are not getting me kicked out!' because when I say they're next door, I mean 15-feet, I don't mean nearby."
Boy George & Sam Smith
Maybe the "Stay With Me" singer got a few performance pointers from Boy George when he bought the London home next to the 80s hitmaker.
Demi Moore, Steven Spielberg & Diane Keaton
For a cool $75 million, you could have cozied up in Moore's Central Park penthouse in the famed San Remo building where a number of A-listers have resided over the years.
Hugh Hefner, Ellen DeGeneres and Portia de Rossi
Who would have thought that in 2014, when the longtime couple purchased a 13,000-square-foot Holmby Hills mansion for nearly $40 million that none other than the Playboy Mansion would be right next door?!
Keanu Reeves & Leonardo DiCaprio
The Oscar winner bought his Hollywood Hills mansion right after his breakout role in 1997's Titanic. Right next door? An equally as talented actor who goes by the name of Keanu Reeves. Casual.
Hugh Grant & Elizabeth Hurley
"It makes us laugh," the actress told E! News of the fascination surrounding their post-break up friendship. "He's my next-door neighbor, godfather of my son, my best friend, but we find it weird. I don't get it."
Kourtney & Khloe Kardashian
Keeping it in the family! Khloe dropped $7.2 million on the impressive abode previously owned by Justin Bieber. As it turns out, Kylie Jenner and Rob Kardashian have also owned homes in the Calabasas gated community known as The Oaks.
Lance Bass, Katie Holmes & Nick Jonas
These stars were all in a New York state of mind when they rented apartments in the 21-floor, über luxurious Chelsea Mercantile building.
Jennifer Aniston & Courteney Cox
Friends forever! In 2006, Jen reportedly purchased a Beverly Hills estate that sat three doors down from her on-and-offscreen BFF.
Justin Bieber, Kourtney Kardashian and & Keyshawn Johnson
In 2014, Kourt purchased the Calabasas home of the former NFL star, who you might recall lived in the same neighborhood as the 22-year-old pop singer (and even got into a confrontation with Biebs over his reckless driving around the area).
Janet Jackson & Bruce Willis
Both the singer and the actor called Trump World Tower in the Big Apple home for some time. In 2014, Jackson listed her lavish crib to rent for $35,000 per month. Lifestyles of the rich and the famous are no laughing matter, that's for sure.
