Budding pop star Paris Hilton is using her new album to talk about her 2007 prison sentence.

The socialite is planning to release a follow-up to her 2006 self-titled debut album, and has been using the songwriting process to open up about her brief stint behind bars.

Hilton, 27, served 23 days of a 45-day jail sentence in June 2007 for violating probation on a 2006 drink-driving charge.

And the star has now penned a track about her experiences in a Californian jail.

She says, "I have another album coming out with a song I wrote like Jailhouse Baby, which is about my time behind bars."
