The Real Madrid and England midfielder was shown a straight red card against Osasuna on Saturday.
Referee Jose Munuera Montero dismissed Bellingham due to an on-field altercation between the pair during the 1-1 draw.
Montero has accused Bellingham of saying 'f*** you' to him, although the England international insists he said 'f*** off'.
The 21-year-old has been backed by former Real Madrid man Rafael van der Vaart, though, in the wake of the incident.
Speaking on Rondo on Ziggo Sport, Van der Vaart explained: "What really annoys me in England is: everyone talks with 'f*** this', 'f*** that', but if I say that on television, I get cancelled."

The host then pointed out that the former Tottenham midfielder had used the word himself on TV recently.
Van der Vaart admitted he had, before adding: "I'm not saying that I've been cancelled, I can still go there, but it's just so hypocritical.
"Everyone talks like that. It's not polite, but it's almost like 'thank you'. Seriously, especially in England."
He continued: "I think 'f*** off' can be said in an emotional moment. It's normal language on a field, even in his own country. I do think there's quite a difference between saying 'f*** off' and 'f*** you.'"

Van der Vaart was not the only former player to defend Bellingham, with Marco van Basten and Mark van Bommel also sharing similar views.
Van Basten said: "I think the red card is exaggerated and really stupid. To get a red card, you should do much more crazy stuff. A yellow card is enough."
Meanwhile, Van Bommel said: "A lip reader needs to be involved here, but a referee will always win this. It doesn't have to be this way, but the federation cannot go against a referee."
The red card was the third of Bellingham's senior career and his second since joining Real Madrid in 2023.
He was previously shown a straight red card for dissent at full-time in a match against Valencia in March last year.
Bellingham also now faces a nervous wait to discover the extent of his suspension as a result of the red card.
League rules on insulting officials state that he could be hit with a suspension of up to 12 matches.
His dismissal also saw Real Madrid play more than half the match with ten men as Osasuna pegged them back after the break.
