Rebel Wilson and her sister used to rap "Will Smith mash-ups".
The Bridesmaids star grew up with sisters Liberty and Annachi and brother Ryot in Sydney, Australia.
The actress used to make the most of having so many siblings by starting a rap group with one of her sisters.
[My siblings and I] were our own gang. We didn't have motorcycles though; we just had BMX," she laughed to Australian radio show hosts Kyle and Jackie O.
"Me and my sister Liberty used to have a rap group. We were out in Western Sydney just rapping it up. We did Will Smith mash-ups like, 'Tik tik boom!' We were like two 11 and nine-year-old white girls. We didn't own two baseball caps; we just had one blossom hat."
Rebel now lives with her Bridesmaids co-star Matt Lucas in Hollywood.
The pair own a Jacuzzi and have been known to annoy their neighbours with some of their antics.
"The neighbours don't like us singing. We have a pool and a hot tub and we like to have fun in it. We like to have other celebrity friends come over and sing musicals," she explained.
"We had a friend from the Les Misérables movie come over, Sam [Samantha Barks] who plays Éponine. Matt's an amazing singer, she's an amazing singer, I try... And we just sing songs. And then the neighbours sometimes don't like it. But we're really good neighbours!"
In musical movie Pitch Perfect, Rebel stars alongside Anna Kendrick and performs 'the mermaid dance'.
The blonde seems to have taken inspiration from her role and sometimes tries to recreate the moment at home in her pool.
"From 8-9pm I call it mermaid lagoon. I put on all the jets and lights - it comes on automatically, I programmed the system - and all the waterfalls come on and I pretend to be a mermaid," she laughed.
"I don't do it every night; some nights I have a life. I do have a costume, but I don't wear that every night, I just wear a regular swimming costume."
