President Donald Trump has fired off a new broadside on social media ridiculing megastar Taylor Swift.

The president mused on Truth Social Friday how the billionaire singer is 'no longer hot.'

The 78-year-old Republican wrote that Swift has seemingly lost popularity - and that he may be the reason for her alleged downfall.

'Has anyone noticed that, since I said 'I hate Taylor Swift,' she's no longer 'HOT?'' the president wrote.

It's unclear what prompted the message sent by the president while he travels back to the U.S. from a trip to the Middle East.
