Devlin quickly responded to Ora's post, which has since been deleted, tweeting
"Sorry Rita, Burgers are nice but not when a man has steak at home."
The Sun reported that during the night the McGregor gave Ora a shout-out as he took the microphone with his pals and took a time out from dancing with the twerking women.
"I asked Conor if he got in trouble for the Rita Ora photos ... He said, 'Do you want a punch on the nose?'" a photographer told The Sun.
"Conor's pals led the women back into the hotel ... when they saw us taking photos they got aggressive," he added.
Ora has been dating musician Andrew Watts since last year who didn't seem overly offended by the reaction.
