THE IRISH actress was soaking up the sights in the Oak-leaf County.
Saoirse Ronan was spotted taking a city tour of County Derry, along with a friend.
Miss Ronan was attending the Martin McCrossan Tour of the city, enjoying the beautiful county of Derry with a Scottish man by the name of Jack.
Speaking to Belfast Telegraph, Charlene Blackburn, the tour guide who assisted Miss Ronan and her friend said she couldn't have been nicer.
Miss Blackburn said Miss Ronan was gearing up to watch the Six Nations in a pub: "She loved the tour and I met her afterwards. She was with a male friend, I think it was her boyfriend...
"And she said that afterwards she was going to Sandinos Bar to watch the rugby. She said she had been in Derry a few times before and she wanted to show her friend how great it was. And obviously to illustrate how great it was she took him on one of our tours, which was brilliant."
Miss Blackburn said the Ladybird actress couldn't have been nicer: "She was absolutely lovely, so grounded and so polite. She posed for photographs no problem, she was so nice. You wouldn't have known she was a Hollywood superstar. She had a big coat and hat on and just looked like a tourist."
