Lady Gaga has hinted that she and Beyonce may be working on a follow-up to their 2010 collaboration on 'Telephone', suggesting that the sequel is coming with two posts to her Instagram account by quoting lyrics before revealing she's writing new music.

Alongside a picture of a pair of shoes, she wrote: "These are my leave me alone heels. My Telephone heels. Stop callin', I don't wanna think anymore. (sic)."

In a second post, she added: "Love you monsters, writing songs. Miss u all the time (sic)."

The track - on which she collaborated with Beyonce - hit number one in the UK in 2010 and has since sold more than 7 million copies around the world.

When originally released, the star teased there would be a continuation of the track by writing, "To be continued..." at the end of the video, although no subsequent song has emerged.

Lady Gaga - who got engaged to long-term boyfriend Taylor Kinney last month - revealed in December she is working on music for her next album, with producers RedOne and Giorgio Moroder reportedly involved in the project.

She said: "I want the fans to be surprised, but I will just tell you that it's a wonderful, soul-searching experience.

"... and it's very unlike the last album in that way. I made that album on the road. 'ARTPOP' was, you know, the acid-making record. And this record is like -- my old self as a cadaver. And I'm just, I'm operating on my old self."
