Our fifth Worst Celebrity Tattoo is another which will happily fade in to memory.

Hollywood actor Mark Wahlberg had four large tattoos, including this bizarre number – his initials, surname and date of birth emblazoned across his shoulder. Why he ever thought this was a good idea is beyond us, perhaps it was a by-product of his drug taking past.

These days, Mr Wahlberg is a family man and has decided to ditch all of his tattoos, having them removed with laser treatment, we’re not sure if he’s using the same clinic as Megan Fox. Having been told he’d need 8-10 treatments to remove his tattoos, but has had over 30 so far and some remains are still hanging on. He describes the treatments as like being splashed with hot bacon fat and much more painful than having the tattoo applied.

Take this as a warning – if while removal techniques do exist and are the best they’ve ever been, they do hurt and can take much longer than even experts predict. Also bear in mind Mr Wahlberg can afford the very best in removal treatment, so his may be quicker than yours would be for the same size tattoo.

Our final worst celebrity tattoo design (hey, it was a bank holiday weekend, and 6 days was good enough for God, yeah?) Here’s a real classic from ‘Jackass’ star Steve-O.

The main thought that appeared in our mind when seeing the tattoo across Steve-O’s back was… Why? Why on earth would you have a portrait of yourself tattooed on your own back?

We can only think it was an interaction between Mr O’s ego and psychological problems, caused by drug use.

Mr O has a large number of tattoos, mainly smaller ones. Should he ever decide to get them removed, we think he could be stuck with this back one. It’s huge, so probably best just left in place. Hopefully his future self will be happy to live with the design.

Of all the dodgy celebrity tattoos that we’ve seen, this wins for sheer, unbelievable ego. We’re still hoping it will be revealed as a big prank on the media.

Another Worst Celebrity Tattoo Design for you, this time on Dennis Rodman’s back.

Mr Rodman is an ex-basketball star and either has a great sense of humour, or is having a long public battle with mental illness, depending on who you listen to. He has a large number of tattoos, but the one we’re focussed on here is the large winged lady with… shaft… covering most of his back.

There’s too much wrong here to list everything: the porn-star fashion, the style of the wings? Horns? Not fitting the style of the model. The previously mentioned… shaft. About the best thing you can say about this one is, he doesn’t have to look at it in the mirror!

Day three of our week of the Worst Celebrity Tattoo Designs, and it’s a cheeky one: Cher’s bottom, with wings.

As a design, it’s kind of fine – flowery wings? Could be tasteful. But on a butt? That’s what you really want to see when you see wings, either a strip of cloth separating them, or worse… nothing separating them. Really, if you’re going to go for this sort of tattoo design, at least be sensible and have them on your back.

Day two of our week of the Worst Celebrity Tattoo Designs, and we say hello and goodbye to Megan Fox’s Marilyn Munro tattoo.

Ms Fox had the tattoo of Marilyn’s face applied to her arm when she was eighteen and now, seven years later, has decided it attracts ‘negative energy’ as Marilyn allegedly suffered from bi-polar disorder (AKA manic depression.)

Ms Fox has had at least two sessions of laser removal and the face is noticeably lighter, but unfortunately far from completely removed. Reportedly, Ms Fox has not been enjoying the laser removal, claiming it hurts much more than receiving the tattoo did.

Please, if you’re eighteen and thinking of getting your first tattoo, don’t make the mistake Megan Fox did. Think long and hard about the design, perhaps get a temporary design first as a test, and think about where it is on your body and what you’ll do about it if you decide you don’t like it in the future.

This week we’ll be showcasing the worst tattoos currently sported by celebrities. These are people who should know better, but ego or addiction to ink has got the better to them.

First up is Tommy Lee.

It’s difficult to know where to start with Mr Lee. He’s pretty much a walking example of why you shouldn’t decorate your body without a solid plan. Independently, some of the pieces of art are beautiful, but they’re rubbing up against things like “Mayhem” scrawled across his torso, and scrollwork across his back. Together, they look like a hotch-potch, and are so extensive nothing is ever going to be able to fix it.

If you must get yourself tattooed, and know you’ll want a lot of them, please: think ahead. Try to rein in your enthusiasm and plan for how you’ll look when everything is done, don’t just pull willy-nilly from the catalogue.

Carl Zimmer is a writer for Discover Magazine, amongst many other things. Having discovered a scientist friend had a DNA strand tattoo with a story behind it, he asked on their blog whether anyone else had science related tattoos.

Many, many people did. He now has a thriving gallery of submissions, and has woven the best images and stories in to a new book, Science Ink: Tattoos of the Science Obsessed.

If you’re interested in the human stories behind tattoos, we strongly recommend having a look through the gallery and clicking some of the images to see the story written up about them. The love some of the scientists and geeks have for their favourite subjects is inspirational.

Want to celebrate the Olympics in London this year, but don’t want to get permanently inked?

We’ve got a range of flag temporary tattoos which are perfect for showing your allegiance for an event, but let you clean it off before getting back to work the next day.

As well as English flag tattoos, we’ve got ones for various European countries and Brazil. Usually people want them for football matches, and you can certainly double up on your order and use them for Euro 2012 as well.

Euro 2012 is on from 8th June to 1st July, and the Olympics starts on 27th July, so any tattoos you don’t use during the cup battle – and lets face it, we might not be in there for long – you can use during the Olympics instead. If we do get through to the cup final and you slather yourself in your remaining temporary designs (do send us some pictures!) you’ll have plenty of time to get some more before the Olympics opening ceremony.

The 5th Brighton Tattoo Convention is being held this weekend. As part of the convention they are awarding prizes for excellent tattoo work done over the last year. And what prizes!
