The way she flips her mortarboard obviously has him overwhelmed: the adorable One Direction star made a secretive appearance at Manchester University to watch his girlfriend Eleanor Calder graduate.
Louis jetted into the city all the way from Barcelona especially for the ceremony.
"He was a bit late for the start of the ceremony and he did not want to create a big fuss," a source told the Manchester Evening News. "He crept in and kept a really low profile. There were around 400 people there at the ceremony and hardly anyone clocked that it was him."

Fellow graduates at Manchester snapped pictures of the heartthrob at the graduation, but the images made it to Twitter only hours later. Witnesses tweeted Louis sat next to Eleanor's mum near the front. The eagle-eyed fans spotted him from far away as he was wearing the same clothes from a photo shoot earlier in the day.

Eleanor, who turns 22 next Wednesday, received a bachelor's degree in sociology after three years of study at the university's Whitworth Hall. She wore a short black dress with a zip down the front under her graduation gown.

The 22-year-old 1D heartthrob has been dating her since 2011, when she was a fresher at Manchester. She once said about him: "Of course I love him. I love him as a person, not as a member of a band."
