The One Direction front man was pictured sharing a plate of spaghetti with Gemma and the actress shared the picture on her Instagram.
Gemma is seeing Harry’s mate Jack Whitehall and she is also friends with his on again off again girlfriend Cara Delevingne.
During London Fashion Week, Harry and Cara were linked again but Harry rubbished the rumours, saying: “She’s not my girl.”
After the meal Gemma tweeted Harry, 19, saying: “Always hungry.”
Gemma is best known for her parts in Sherlock and The Secret Diary of a Call Girl.
Harry is currently with One Direction on tour in Australia and earlier this week his band mate Liam Payne had to tell fans who were waiting for the band to get out of a snake-infested field.
He tweeted: “Girls behind the hotel please get out the fields there’s a huge sign saying snake habitat it’s just not worth it someone’s gunna get hurt.”
Just to make sure their fans could tell he was being serious, Liam tweeted again: “Are you not reading what I’m saying it’s a SNAKE HABITAT TURN AROUND.”
