A former Celtic starlet has been accused of sending his girlfriend a series of disgusting messages, boasting about cheating and mocking autism.

The girlfriend of Theo Archibald, who now plays for Championship side Brentford, has publicly shamed the player by sharing the messages.

Jennifer Lewis posted screenshots of the messages on her Twitter page with the caption: "Found out my boyfriend of 2 and a half years had been cheating on me for 8 months footballers eh”.

The Snapchap messages apparently show the Scotland U19s star poking fun at autism and boasting about sleeping around.

In the messages, Jennifer seemingly quizzes Archibald about flings he allegedly had while they were in relationship.

When asked who he slept with, the young football star replies: “U asked who she was, I said she was autistic hahaha.”

Archibald then apparently goes on to discuss his affairs and in one foul-mouthed exchange admits: “Yea I f***** her too.”

He also claims he slept with a female he met in the Czech Republic during a trip with Scotland's U19s team earlier this year, reports the Daily Record .

“She was the person that showed us about etc. But obv she had a liking to your boy so found me and messaged me on FB", Archibald gloats.

In the next message, he then goes on to boast about a fling he had in London.

Brentford confirmed the club has launched an internal investigation into the matter.

Archibald, 19, signed for Brentford in the summer, making his first-team debut on the 2-0 defeat against Ipswich in August.

The midfielder has made just two more appearances for Dean Smith’s side, but is a regular for the Championship outfit’s Under-23s.

Archibald came through the ranks at Celtic and spent time on loan at Albion Rovers earlier this year before his move to Griffin Park.
