Miley Cyrus' ''true love'' is marijuana.

The 25-year-old singer - who is engaged to Liam Hemsworth - is currently abstaining from the drug because she is ''very focused'' on her work, but she's expecting to pick her habit back up at some point.

Asked if she's currently smoking weed, she said: ''I want to be, but no. I am very focused on what I'm working on right now.

''[Weed is] the most magical, amazing thing. [It's] my first and true love.

''It's just not for me at this time in my life. But I'm sure there will be a day that I will happily indulge.''

Though the 'Malibu' hitmaker likes to snack when she's ''stoned'', she won't be indulging in a special packet of peanuts which she's held on to from a flight 15 years ago.

She told talk show host Jimmy Kimmel: ''They mean something to me! They represent the beginning of this life for me because I was on my way to LA for the first time to audition for 'Hannah Montana'.

''My dad was there, my dad was in first [class] and I was in coach and he said he'd throw me a hot peanut from the classy section. And then I said, 'I already have my own.'

''So I've just kept them with me forever. No matter how stoned, I don't snack!''

The peanuts aren't the only memento from her past that Miley's held on to as she admitted her ''hoarding'' drives Liam, 28, crazy.

She said: I would say that I'm a clean person, but I'm also a bit of a hoarder - he calls it hoarding, I call it collecting.

''That thin line that divides hoarding and collecting is keeping things in the package, so having things in the boxes.''

The 'Voice' star recently shared a clip of Liam scaring her at home and she admitted the 'Hunger Games' actor has a bad habit of sneaking up on her.

She said: ''I know that it's May and I was putting our Christmas decorations away finally.

''I was already in this really creepy basement and I was coming up to say, 'Oh my god, that basement is so scary.' And then he jumped out at the worst time...

''I just don't know why I haven't caught on to this at all. I just don't know he's around every corner. He's around a lot of corners.''

But Miley hasn't been so successful at returning the prank.

She explained: ''I'm obviously loud and so I'm not very good at scaring people.''
