Amber Rose and Wiz Khalifa

Wiz Khalifa claims Miley Cyrus "smokes a ton" of marijuana.

The 26-year-old rapper, who was arrested for multiple drug charges in 2010, recorded several songs with the former Disney star for his new album 'Blacc Hollywood' and admits he was surprised by how much they had in common.

The 'We Dem Boyz' hitmaker told 'The Arsenio Hall Show' on Monday (30.03.14): "I got some songs with Miley on there."

Asked what it was like to work with the 'Wrecking Ball' singer, 21, he said: "Insane! But in a good way though, she's just a ball of energy. She smokes a ton."

Wiz, who has 13-month-old son Sebastian with his wife Amber Rose, claims he couldn't keep track of how much Miley was smoking.

He explained: "I don't know. She's younger so it's different. Every five minutes she kept being like, 'Hey Wiz, you don't have a joint rolled? What's up?' She was just blowin' like a train."

The 'Adore You' singer has frequently admitted she is a big fan of the drug in the past.

The controversial young star previously said: "I think weed is the best drug on earth! One time I smoked a joint with peyote in it, and I saw a wolf howling at the moon."

Wiz and Miley have a close friendship as his wife was previously managed by the singer's mother, Tish Cyrus.
