Squealing with delight, she told him: “I will try and control myself!”
She then proceeded to ask him a series of questions about the upcoming fourth series, while Phillip Schofield sat back, clearly amused.
At the end of the interview she stood up as Phillip took a picture of them – unable to hide huge smile.
Holly gushed: “So nice to meet you.”
Those watching at home found the whole interaction very funny and took to Twitter to comment on it.
One person wrote: “Holly’s dream just came true and Phil had to drag out a photo with Sam Heughan #ThisMorning.”
Another added: “Love watching Holly fan girl over @SamHeughan . To be fair he is an absolute dream 😍 #ThisMorning.”
While someone else Tweeted: “#thismorning Holly, wipe the dribble off your lip you.”
Sam, 38, is a Scottish actor best known for his role in Outlander, which he joined in 2013.
The show, which is based on a series of bestselling novels by Diana Gabaldon, follows Jamie’s romance with the World War II nurse Claire Randall (Caitriona Balfe) as she travels back in time to 18th century Scotland.
Outlander Actor Sam Heughan has written the foreword to an excellent book “There’s always the hills ” by Cameron Mcneish , in which he gives a little clue about the location of the famous standing stones –
” We had been filming Outlander near Loch Rannoch for a few days, among the magical setting of standing stones that the main character Claire travels through, back to Scotland in 1745. I had spent my 35th birthday on the side of a mountain, filming a ‘picnic’ in the driving rain and fog, and even the bannock we had to eat was soggy. Dreich and damp as we were, it felt momentous, remarkable even, the ever-changing summit of Schiehallion standing like an extinct volcano, cloud continuously
masking then briefly revealing her sharp peak, the magical backdrop to our scene. I looked towards where I knew our crew would be working, at least a kilometre down, in the valley. The wind was getting stronger but the snow had eased. As if in answer, the cloud briefly parted allowing me to see down the long sweep of the valley to a silver-grey loch in the distance. I could make out the circle of trees that marked the location of the standing stones, the cherry picker cranes carrying the enormous lights that pretend to be a dim Scottish sun. I even spotted a few black figures, unrecognisable in wet weather gear, moving slowly around. The crew would be cold and wet and only halfway through their day and I felt so fortunate to have the time off. As quickly as they had parted, the clouds closed again and I was alone. It was time to get down, in case the weather got worse and I lost my way.”
