Lady GaGa held back a new song she has handed to TLC stars Tionne 'T-Boz' Watkins and Rozonda 'Chilli' Thomas because she feared it sounded too much like a Tlc tune.

The Paparazzi singer has written Posh Life for the duo's comeback but the Waterfalls singers reveal Lady Gaga originally penned the song for herself.

Watkins says, "She was like, 'I don't want to disrespect the girls'. We were like, 'Let's sing it and see how it goes. I mean, you wrote it.' It was so funny hearing her sing like us... I was just like, 'Why not sing it then?' She was just like so excited and we're excited."

Thomas and Watkins are now hoping their new pal will join them in the studio: "She wants to, (but) you know them record company people. If it was up to the artist, all three of us are down. So we'll see what happens."
