A sperm!

There is always a debate about getting tattoos as sceptics often feel that people will eventually regret it, and as it's permanent you probably don't want one you'll regret later. We all know someone who went off to Magaluf and got something written on their bum or a cartoon character on their hip, but they all seem pretty tame compared to Mandy Moore's bizarre tattoo. The actress rarely makes headlines due to her somewhat tame and normal lifestyle, so we were surprised to see that she has a tattoo of a sperm on her foot. Mandy shared the tattoo on Instagram over a year ago stating that her stunt double had to have it drawn on to make her more similar to the actress. https://www.instagram.com/p/4OX-RHDXVo/ So if you're wondering why in the world Mandy decided to get a tattoo of a little swimmer on the side of her foot, you're in luck, as she finally explained it. Speaking on chat show Late Night with Seth Myers she explained that she got it as a joke almost a decade ago when she was in a band.

“About 10 years ago, I was on tour with my band,” she explained. “When you go city to city, you’re on a bus, but you get a day room [in a hotel]. I was the only girl, so I had my own room to shower, and all the guys in my band shared a room."

She explained that the boys in her band had a rule about no one being allowed to masturbate in the shower.

“It became this big joke, because one of my band members was like, ‘I don’t want babies on my feet,’” she said. “And so we created a song called ‘Babies on My Feet’ that we sang onstage every night that no one had any idea what we were talking about.” "To commemorate the tour we all got babies on our feet." She added.

The actress who was promoting her show This is Us which also stars Milo Ventimiglia, then proudly showed off her tiny tatt.

We're no experts on the matter but we reckon you could easily turn that into a little daisy or a balloon or something a little prettier, just a suggestion Mandy...
