Styles has had "never gonna" just above his right foot and "dance again" on his left, lyrics from 'Careless Whisper' by Michael's former band Wham!
The inkings join Styles' other works of body art including a large butterfly across his ribs, two birds on his chest and a ship on his left arm. Harry and his friend Ed Sheeran also have a matching tattoo of Pingu, a penguin from a children's TV series.
The 19-year-old singer showed off his latest inkings as the band - which also includes Louis Tomlinson, Niall Horan, Liam Payne and Zayn Malik - relaxed in Miami ahead of the first show in the US leg of their Take Me Home world tour in Florida.
