The 29-year-old singer said she decorates all the firs with different themes – including an Asian tree, a “theatrical” tree and a cartoon tree.
“For my bedroom it’s a sort of Asian theme, because I have an obsession and love for Japan,” she said.
“For my theatre there’s a more theatrical theme, where you have ornaments that revolve around Marilyn and movie stars.
“For the game room tree, which is like the main one in the house, you have ornaments that revolve around really fun cartoon characters. It’s a free-for-all.
“Then you have the foyer tree that is very homey and earthy. It’s got mittens and cosy things. I get it from my mom. I’m very festive.”
