No matter how many dignitaries, ambassadors, Prime Ministers and regular celebs you've met in your life, it seems all it takes is one glance from Ryan Reynolds to knock you for six.

As the daughter of US President Barack Obama, 14-year-old Sasha Obama hasn't exactly had an ordinary upbringing. But just like most teens her age (and adults, let's face it), she's a big fan of Mr. Reynolds.

And after coming face-to-face with the *disarmingly* hot actor during the Canada State Dinner at the White House last week, poor Sasha got a bit flustered.

Vancouver native Ryan attended the event with his wife Blake Lively, but found a few minutes to chat with the President's youngest daughter before sitting down to dinner.

This candid snap, which shows poor Sasha looking like she's about to melt with excitement as she chats with Ryan, has been doing the rounds on the internet all weekend.

There's just so much to love about it – Sasha's uber-starstruck face, Ryan's 'let's have a serious conversation, shall we?' expression and, of course, 17-year-old Malia Obama being the cheekiest big sister ever in the background.

She might be a bit blurred out, but there's no mistaking that massive smirk and thumbs up that Malia is throwing in her little sister's direction:

We bet the unmerciful slagging is STILL going on, four days later.
