The One Direction singer visited a parlour in Dorset to top up the growing sleeve design on his right arm with some new ink and was joined by Perrie's brother Jonnie.
However, 21-year-old Zayn was so concerned that fans would try and sneak into the room while he was being tattooed that he asked for the door to be locked behind him.
Unlucky for Perrie, this meant she was unable to get in later on and was reportedly forced to wait for her man and her brother in a pub nearby.
Tattoo parlour owner, Paul O' Connor said: "Perrie's brother Jonnie, popped in an hour before to ask if we could fit Zayn in.
"When Zayn arrived we had to lock the door because last time there were a crowd of screaming girls outside who kept coming in. There were just two girls stood outside this time. They saw him come in and waited until he left. We had to pull the blinds down to stop them looking in.
"He was here for about an hour and a half with Perrie's brother and a couple of other friends. He was relaxed and talkative. He said he and Perrie had a quiet New Year but he had a busy year ahead. I couldn't get a wedding date out of him".
The One Direction band member - who celebrated his 21st birthday at Disneyland this week - had also paid a visit to Tattoo Magic in Dorset last year, when he had an inking of a wolf etched onto his leg.
He has a number of other designs on his body, including a tattoo of future-wife Perrie on his bicep.
The loved-up pop stars got engaged last August, but have yet to reveal any details about their nuptials or when they are planning to walk down the aisle.
