Calvin Harris has thanked One Direction's Liam Payne for "saving" him after a flying dwarf soared towards him at Miley Cyrus' 21st birthday party.

The Bangerz star was celebrating her milestone at Beacher's Madhouse nightclub in Los Angeles after performing at the MTV American Music Awards.

She sung "Wrecking Ball" wearing a skimpy cat-printed leotard in front of a giant kitten earlier that night.

But she forgot to warn guests of hazardous party entertainment that nearly saw the Scottish DJ knocked out.

Harris tweeted his gratitude to the "Best Song Ever" singer on Sunday.

Country singer Billy Ray Cyrus reportedly presented his daughter with a personalised three-wheeled motorbike at a party featuring dancing pandas, twerking girls doing the splits and Miley-themed cocktails.

Other guests included Payne's One Direction bandmate Niall Horan, rapper Wiz Khalifa and Kelly Osbourne.

Cyrus rented out the whole club for her first night as a legal alcohol drinker and enjoyed a birthday cake decorated with her naked body covered in marijuana leaves.

Following her performance at the MTV Europe Music Awards in Amsterdam earlier this month her love for the illegal drug has been widely-known. The singer lit a joint on stage when accepting the award for Best Video.

She is also a fan of dwarves after twerking and spanking with 'Little Britney' during a performance of "We Can't Stop" at the same November event.
