Hollywood homes with bizarre features - including John Travolta's personal airport

Paris Hilton famously built a miniature house in her garden for her pet dogs. The design was based on her own luxury mansion, complete with air conditioning, a balcony and even a chandelier. The incredible creation is believed to have cost an eye-watering $325,000! Talk about a puppy palace!

Singer Lady Gaga hasn't actually got bats flapping around her home, but she does have a secret underground lair, accessed by tunnels. It has a movie theatre, bowling alley and arcade games. It won't surprise you to learn that the former owner worked for Warner Bros.

John Travolta has a serious passion for planes, and he demonstrated that by buying his very own runway in Ocala, Florida and building a house on it. His $10 million Jumbolair Aviation Estates residence has space to park two of his jets right outside, so he can board his private jet within a minute of leaving his front door.

While the legendary singer currently lives in Las Vegas, she used to live in a majestic property in Florida, complete with its very own waterpark. Back in 2008, Celine and her late husband René purchased a five-acre plot of land which they slowly transformed into their dream home. We're sure her three sons, René-Charles, Nelson and Eddy, loved it!

Beyoncé and Jay-Z's Bel-Air mansion, designed by architect Tadao Ando, has all the luxury features you would expect from an A-list property, like a pool and a gym. But there's also a dedicated art gallery on site, and the works on display include ones by icons Warhol and Basquiat. Fun fact: Their almost $90 million property was the highest real estate transaction ever in the area at the time!

The Kardashian/Jenner clan have seriously impressive properties, with an endless list of wow-factor features, but nothing is more intriguing than Kris' hobby haven. The famous momager has an entire room dedicated to crockery. Yes, you read that right. Her fine china display includes designer sets sourced from all over the world, including a $640 Gucci teapot! And in true Kardashian/Jenner style, it is immaculately arranged at all times.

We know celebs like to party, but how about having a club in your home? When Big Sean opened the doors to his Beverly Hills mansion to Architectural Digest, he revealed his legendary nightclub. It was already part of the house when he bought it, and the all-black room has a DJ booth, disco ball and wall-mounted skull lights. At least his post-club trip home is just making his way upstairs!

Michael Jackson's Neverland in Santa Barbara, California, made headlines all around the world. The full-blown amusement park featured a rollercoaster, Ferris wheel, carousel, and bumper cars. The site has since been renamed Sycamore Valley Ranch and is currently owned by Californian investor, Ron Burkle.

Microsoft co-founder Bill Gates is known for his billions so it seems only logical that he would have an impressive home. His lavish property, known as 'Xanadu 2.0' is believed to be worth a dazzling $130 million. Located in Medina, a suburb of Seattle, the place is a high-tech haven where guests are tracked upon arrival and rooms adapt to their temperature preferences. While having a trampoline in the garden is fairly commonplace, Bill has taken it one step further with an indoor trampoline room!

Not as extravagant as the rest, but rather epic, nonetheless. When Gwen Stefani and Blake Shelton got engaged, they shared a picture from their private place of worship on Blake's Oklahoma ranch. They then went on to get married there with friends and family watching on. Gwen and Blake's country bolthole is where they like to spend a lot of their time, partaking in wholesome pastimes like gardening together. So sweet!
