Lady Gaga has been working on new material with producer Mark Ronson, according to reports.
The pair are believed to have spent time together in a London recording studio during Lady GaGa's recent UK tour with the Pussycat Dolls.
“They worked on a couple of tracks which have a vintage feel,” a source told The Sun newspaper.
Beside his solo career, Ronson is best known for his work on Amy Winehouse's second album 'Back To Black'.
As previously reported on Gigwise, Lady GaGa's two week reign at the top of the UK charts was ended last weekend by Lily Allen.
