The boyband star spent the day making friends with a host of furry critters, where he fed meerkats, met monkeys and came face-to-face with a tiger.
It wasn't a spontaneous trip for Max, as headed to the Welsh Mountain Zoo in Colwyn Bay, Wales on Tuesday (16 July) for his brother Jack's birthday.
The visit was also a trip down memory lane because Max used to go to the same zoo when he was a child. The 24-year-old got stuck in with the animals, feeding the meerkats by hand and getting up close with the zoo's resident tiger.
Speaking to the Daily Post, Max said: "We got to feed the tigers, which was awesome. I didn't think it would be that close, it was like inches. It was amazing - definitely the best bit of the day."
Later taking to Twitter, Max told his followers that he had an "amazing day". The singer is currently back with his band mates, preparing to perform in front of fans tonight (18 July) to headline Rochester's Castle Concerts.
Max has recently been linked to TOWIE's Lucy Mecklenburgh after they were seen canoodling in a London nightclub last month. The lothario has kept tight-lipped about their romance but Lucy has since spoken and told Reveal: "It's really early days," adding, "I do like him, he's hot!"
