Millie Mackintosh and Hugo Taylor were turned away from the VIP area at Glastonbury.
The reality TV stars were left red-faced after showing up at the main hospitality area of the festival on Friday (24.06.16) without the correct wristbands and it took some time to sort out the situation.
A source told MirrorOnline: "It was a bit embarrassing when they tried to get into the area and a member of staff told them they had the wrong wristbands on.
"They were stood at the entrance for a while trying to get in and Millie took her phone out to try and call someone.
"Hugo then went up to the hospitality reception to attempt to sort things out. In the end they managed to get the right bands and headed into the area."
However, the drama did not end there as a fellow festival-goer spotted the pair once they got inside the VIP area and shouted out questions about Millie's former husband Professor Green.
The insider explained: "A reveller shouted 'Are you back together? I hope Pro Green is here!'
"Thankfully the pair didn't hear the outburst and continued to head into the area oblivious while hand-in-hand and went to the bar."
Millie and Pro Green, 32, split in February after less than three years of marriage and received their decree nisi in just 30 seconds at a hearing at the Family Court in London last month.
Announcing their split in a statement, they said: "It is with sadness and regret that we confirm our separation.
"It is a mutual decision, we still care deeply about each other and would like it to be known that it is on amicable terms and we wish each other well."
And it wasn't long before Millie rekindled her romance with her ex-boyfriend and former 'Made In Chelsea' co-star Hugo, 30.
A source previously said: "From what Millie is saying it seems more than just a rebound. She's being quite coy about it but she's really excited and loving being around Hugo again. Everyone knows he was her first love and she seems to be falling for him again."
