Adam Lambert has admitted that he can't choose between Madonna or Michael Jackson.

The singer recently took part in the 'This or That' quiz with Warner Bros New Zealand.

At one point the US star was asked to pick his favourite between Madonna and Jackson.

However, he said: "Can't do that. You just can't pick one."

Lambert did pick tattoos over piercings and 80s music ahead of 50s music.

The singer meanwhile recently announced that he will feature in a TV remake of The Rocky Horror Picture Show.

The singer will play the part of Eddie in a Fox overhaul of the 1975 film.
