Singer-actress Kelly Osbourne has discovered the benefits of colouring. She says she finds the process "meditative".

The 31-year-old took to Instagram on Saturday to share that she has found something that has been proving incredibly helpful for keeping her mind calm, reports femalefirst.co.uk.

"I finally understand why my dad spends so much time painting! Even though this is clearly a colouring book... It's like meditation. Before I knew it, an hour went by and all I filled in was a bloody (leaf emoji). I don't have very good patience and I think I just found my cure," Osbourne wrote on the photo-sharing website.

She later posted a shot of the adult colouring book "The Bad Bones Club", after her fans rushed to ask her which she book was using.
