Harry Styles parties with students hours after Taylor Swift flies to Germany
The One Direction singer - who'd been enjoying a romantic break with country singer Taylor - turned up at a friend's party in the university city at 1.30am on Saturday.
And of course his arrival didn't go unnoticed.
In a few candid photos from the bash, Harry is surrounded by excited girls and happily poses with the star-struck guests.
The 18-year-old is said to have spent three hours at the student event charming the students.
One girl claimed about her friend on Twitter: “He told her she was very attractive and to take off her Minnie Mouse suit lol.”
And when another friend replied: "He's with taylor swift!!" a third girl responded: "nott annnymmmorreeee."
Harry even got his hands dirty doing the washing up and revealed his favourite song is Beyonce’s Single Ladies.
Student Georgina Dick Tweeted: “We also talked about whether he would have gone to uni and football teams while we washed up together."
Another guest, Bethany Chapman, wrote: “Best day of my life!
“Chilled with him for like 3 hours!!! I was literally in shock the whole time, trying to play it cool haha, but inside i was freaking out!!!!!”
A source claimed to The Mirror that Harry - whose sister goes to university in Sheffield - "dropped by as a favour for a friend".
Though he probably had his pick of girls at the party, Harry's clearly smitten with Taylor, who's now flown to Cologne.
Last week the loved-up pair took time away from their hectic schedules for a relaxing break in the Lake District, followed by some quality time with Harry's family.
The pair also celebrated Taylor's 23rd birthday, when Harry is reported to have presented her with 23 cupcakes and a Burberry handbag.
They later enjoyed lunch together in a country pub. Cute!
