Christina Aguilera has rediscovered her love of piercings - and can't wait to get more body parts adorned with jewellery.

The 'Beautiful' singer - who at one time had as many as 12 body piercings - shared a photo of herself getting a new hole in her right ear lobe with her Twitter followers.

Christina, 37, captioned the photo: "Forgot how much I love getting pierced ... so euphoric for me ... wonder what else I should get done again [sic]"

The 'Dirrty' singer once had 12 body piercings, including her in her vagina, navel, tongue, lower lip, ears and right nipple.

Coincidentally the piercing of a woman's upper labia is known as a Christina piercing, after the first woman known to have had one, in the 1990s.

But the pop superstar - who is mother to 10-year-old son Max and three-year-old daughter Summer - took them all out except for the one in her nipple.

Christina said back in 2004: "I'm rebelling against myself. I've taken out all of my piercings apart from one in my right nipple. That's for me. I had piercings when I was down. There's a comfort to me in pain." 

The 'Genie In A Bottle' hitmaker recently revealed she carries an emergency DVD player everywhere.

Christina loves watching "mood-driven and inspiring" movies such as 'Frida', 'Whatever Happened to Baby Jane?' and 'Amadeus' before she goes to sleep so always has the films with her.

And just in case "something goes wrong with technology", Christina makes sure she has a back-up device to play the discs on.

Christina has been in a relationship with fiancé Matthew Rutler - father to Summer - for eight years. Her son Max is from her marriage to Jordan Bratman.

She will next appear in the romantic sci-fi film 'Zoe' with Ewan McGregor and Lea Seydoux, due out this year.
