Instead of letting them know their mistake, he decided to see how much he could get away with while they thought he was 'Anna the Slamma.' Anna just wanted to go to the spa and get wasted.
Luke told Metro that he managed to keep the charade up for two days before one of the girls called his number and heard his voicemail.
"My intention was to keep going in the hope I could get the ladies something for their hen party. But I’ve messaged the group admin, she was sweet and saw the funny side."
Looks like Anna the Slamma won't be able to tag along.
