Pop star Lady Gaga has shared a series of photographs on photo-sharing website Instagram while getting tattooed and she is seen baring her derriere in one.

The singer who calls her fans Little Monsters and herself Mother Monster paid homage through getting a tattoo on her back.

The 28-year-old, who is currently travelling round Europe on her hit ArtPOP tour, shared it with her followers on Thursday, reports dailymail.co.uk.

The singer seems to be in Hamburg, Germany for her session with tattoo artist Eric Gonzales of Deer's Eye Studio, where she flashed her behind in one of the shots of the procedure.

Gaga had dressed down for her time with the tattoo artist, who she perhaps flew in specifically for the job as he is based out of U.S.

She wore a basic grey dress which she hoisted up and down to reveal the majority of her body for the series of revealing shots.

The tattoo appeared to be a monster hand or paw complete with long nails and a scaly wrist.

"Uh Oh...it's time monsters," the `Poker face` hitmaker wrote in a caption alongside the first image of her tattoo session, adding: "Paws Up."

"Getting some very important ink from the the great @Nspired1 ...it's time #monster4life,' she wrote in another caption.
