Billie Piper thinks the tattoo she got to commemorate her marriage is "disgusting".

The actress admits she regrets having the inscription on her forearm, which reads 'mr fox 31-12-07' but has not made any plans to have it removed.

She said: "It's disgusting. He's got 'mrs fox'. We were in Mexico and both so drunk. I think we both regret it now.

"The thing is, I just look at it and think, 'God that's vulgar.' I don't know what I am going to do about it."

Despite still professionally using her maiden name, the 27-year-old star insists there was never any doubt that she wouldn't take on Laurence's surname when they married.

She explained to Marie Claire magazine: "Laurence was like, 'If you want to call yourself Billie Piper Fox, that's grounds for divorce.'

"Also, I really admire a woman who takes her husband's name and gets rid of her maiden name, but I can't for work. It reminds me too much of my dad. And I think a double-barrelled name is a bit w**ky."
