Lady Gaga hints at 'Telephone' follow-up

Pop sensation Lady Gaga has hinted she is working on a follow-up to her 2010 single 'Telephone'.
The 28-year-old singer suggested the song's sequel in two posts on her Instagram account, in which she quoted lyrics to the chart-topping track before revealing she is 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 you 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 seven million copies around the world.
