Guess which stars are celebrity neighbours in the Hollywood Hills?!

As the song goes, everybody needs good neighbours. 

But if you're an A-list star, you probably don't want mere mortals living beside you; so that might be why these celebs have chosen to all shack up beside each other. 

So whether it's Elton John and Courteney Cox or Niall Horan and the Kardashians, we're wondering who lends each other a cup of sugar… because good neighbours become good friends:

Ellen DeGeneres and Hugh Hefner

Most people worry about noisy neighbours, but Ellen didn't seem to mind when she found her dream home right next to the Playboy Mansion. 


Miley Cyrus and The Wests

We wonder if Miley will be on-hand for baby sitting duties when Kim and Kanye go out?


Khloe and Kourtney Kardashian

After Khloe split from Lamar (but are reportedly getting back together now), she snapped up Justin Bieber's old house in Calabasas, California, right next to her sis, Kourtney. 


Katie Holmes and Nick Jonas

Katie moved into the plush Chelsea Merchantile Building with her daughter after splitting from Tom Cruise in 2012. But earlier this year Nick Jonas decided to rent the flat next to Katie (for a steep €19,000 per month).


Meryl Streep and Gwyneth Paltrow

Gwyneth is officially the best neighbour ever. After Meryl's oven broke last Christmas, Gwyneth let her use her apartment to host a family feast, even though she wasn't there at the time. #NeighbourGoals


Ant McPartlin and Declan Donnelly

Not only do Ant and Dec work together, the live across the road from each other. And not only that, they also bought two villas beside each other in Portugal so they can holiday together too.


Elton John, Brody Jenner, Courteney Cox and Lily Collins

Sierra Towers is clearly the place to live in West Hollywood. Imagine bumping into these celebs on your way to work! Past residents include Frank Sinatra and Joan Collins. 


Niall Horan and the Kardashians

Could Keeping Up With One Direction be hitting our screens soon? Probably not, but Niall might just pop up in the background of KUWTK after buying a house beside the famous reality family. 


Liz Hurley and Hugh Grant

Most people can't get far enough away from their former flames but this ex-couple are so keen to remain friends that they live beside each other. "We were together for 13 years and then we've been best friends for 15," said Liz.
