Saoirse Ronan had a pretty random question put to her by W Magazine but she totally went with it in this pretty adorable video. 

The 21-year-old Carlow actress was asked to name her favourite sex scene in a film and then went on to describe the clip in hilarious detail. 

The Brooklyn actress totally owned it though as she described a comedic scene been Kristin Wiig and Will Forte in 2010 comedy film MacGruber. 

"I think it's wonderful," said Saoirse as she dons an inexplicable peroxide blonde wig. 

"That always makes me laugh." 

Saoirse is currently on a pretty exhausting press stint ahead of her nomination at the Academy Awards which takes place next month. 

Watch the exact scene she is describing below:
