Man's photo of his girlfriend goes viral for a rather embarrassing reason

A man in the US couldn't resist including his girlfriend in the photo of a shirt to send to his mum - sadly, he inadvertently revealed far more about the relationship than he wanted to.

Maison Vallance, 22, innocently posted the photo to Twitter of his girlfriend posing in bed with the shirt his mum had bought him.

"I took this picture to let my Momma know I found the shirt she got me, but Meghan is too pretty not to post It," he added as a caption.

The photo quickly went viral with people pointing out the hilariously embarrassing item that could also be seen in the shot.

Once Twitter users pointed it out, Vallance quickly acknowledged what he'd done.

Luckily for him, both his mother and his girlfriend seem to have a good sense of humour.

The man told Indy100 his mum found it "hilarious" and his girlfriend was "embarrassed at first but then embraced it".
