Heidi Montag 'writes 13 songs in a day'

Heidi Montag has claimed to have written 13 songs in one day for her new album.

The Hills star, who last month announced that she was working on a new record, posted a series of messages on Twitter yesterday while she worked on the LP.

She wrote: "Drinking hot tea enjoying a relaxing Sunday morning writing songs for my new album...I am writing all my songs from now on (sic).

"wow i wrote 13 songs today!!!!...working hard and i love it!!!!!!!!!!!!!!!!"

Montag released her debut album Superficial in January this year. It was reported to have sold 658 copies in its opening week.
