Nicki Minaj says she'll definitely be "signing a few boobs" on her album promotion dates.

The rapper is currently promoting her second studio album Pink Friday: Roman Reloaded, which is due for release next month.

Nicki is famed for her over-the-top and eccentric behaviour, and has promised fans that her extrovert personality won't falter at her album signings.

The star replied "yes!" to a Twitter follower when asked: "Will u be signing a few boobs during the album signing too? :D (sic).

Nicki answered a range of fans' questions on the social networking site.

The 29-year-old hip hop star admitted that her second album was much less complicated to produce than her debut record, Pink Friday.

"Yes! So much easier! Love it! (sic)" she exclaimed in response to a fan asking about the album being "easier to put together" second time round.

Despite her revelation, Nicki revealed that she has still come across a few difficulties while editing her songs.

"Editing #BeezInTheTrap and #Starships smdh....(sic)" she said, with "smdh" an acronym for shaking my damn head'.

When a fan replied: "why smdh'? Is it stressful?" she added: "Very."
