Demi Lovato, Avril Lavigne and Ashley Tisdale are recording soundtrack for the ultimate Disney Princess animation

This was tat no.16 for Miss Cara, who hired Los Angeles artist - Dr Whoo - to ink her. It's a coat of arms that features the letter 'D' - for 'Delevingne' we presume.

Demi debuted a ribcage tattoo [OUCH] of five lines of roman numerals. Each line of text appaz stands for a family member's birth date.

This tat is supposed to represent that Rita and childhood friend, Anda, will be ballerinas until they're 102. Sweet.

The former Girls Aloud singer has the words 'don't be bitter - glitter' scrolled across her back. Well tatt'd, Sarah.

"Love, truth and power" is the definition of Li-Lo's tattoo. She wrote on her website: "Wanted you guys to see it first. Feeling good and love you

So many tatts we had to include her again. This forearm inking says, 'I restore myself when I'm alone'. Chill at home with a good book style.

The footballer's wife got sentimental with her sister Victoria when they got matching dove tattoos on their ankles. Frankie tweeted: "Painful sister love by the awesome...Freddy Negrete."

This one has extra sentimental value. Emma Stone got this tattoo to celebrate her mum beating cancer. It was also designed by Sir Paul McCartney himself. The design includes two black birds, which represent both her and her mum and stem from their favourite Beatles song, Blackbird.

Selena's tattoo artist, Bang Bang, explained: "The tattoo was a tribute to a family member who she said means a lot to her." The tattoo reads "LXXVI" which is the number 76. Selena's mother Amanda Teefey was born in 1976.

Aside from it being huge and under her boobs - this piece of permanent body art, represends a goddess and is in memory of her late grandmother. RiRi said: "Goddess Isis - Complete Woman - Model for future generations #GRANGRANDOLLY - always in and on my heart." Lovely and sentimental.

On her right hand she has the words 'Trust no one' and on the other, the word 'Paradise'. Independent, strong, but maybe trust some people though, eh Lana?

On her right wrist Jessie has 'Stand Up' inked with a heart. We're guessing it's something to do about standing up for what you believe/stand up and be stronge/when you're knocked down stand back up again? Either way, we like.

To celebrate T's 27th birthday today, we've found 15 other female celebrities with strong, positive, inspiring tattoos. Here's Tulisa's 'The Female Boss' one to kickstart the occasion...

Another mum-related tattoo here - but who doesn't love their mum? Adele has 'One Penny' tattooed on her wrist. The singer's mum's name is Penny, so it must be because of that. Aww.

Sienna's permanent red carpet accessory comes in the shape of three little stars on her right shoulder. They are said to symbolise love, honour and trust.

'Born This Way' is a dead giveaway and totally describes Lady GaGa. We're translating this as; celebrate who you are and don't worry about who's watching.

And this one...just because.
