Adam Levine On Christina Aguilera's Weight: 'I'm Keeping My Mouth Shut'

The Voice judges Christina Aguilera and Adam Levine are rumoured to be at war, and it could have got much worse as the Maroon 5 singer was asked about Aguilera's weight by Howard Stern.

Christina's weight has been criticised around the world in recent years, and Kelly Osbourne has been very vocal about it - and now Howard Stern wants a word.

When Adam dropped in for a chat with the shock jockey, he asked: Why do you think she got so heavy Is she upset? She used to be so f**king hot! When youre a plus-sized woman, you cant wear the tight clothes anymore.

A speechless Adam, looked visibly shocked by the line of questioning, and shook his head. He then added: I wouldnt go that far."

But not content with that Stern continued: Adam, what size is she?, before insisting that Aguilera was now a US size 12, which is a UK size 16.

To which the 'She Will Be Loved' singer replied: Im keeping my f**king mouth shut.

Do you think Howard Stern was out of line? Or was he just asking what everyone was thinking?
