One Australian Beyonce fan got the mother -- make that QUEEN -- of all concert souvenirs last week, when Queen Bey herself "photobombed" the teen's selfie in the middle of a song!

Beyonce posed for the amazing photo during her Mrs. Carter World Tour stop in Melbourne last Friday (Oct. 25). She was in the middle of singing "Irreplaceable" when the pic was snapped -- and true to Bey's flawless nature, she never even missed a beat!

The fan who took the photo, 15-year-old Valentina, posted it on Instagram, causing a sensation that rippled throughout the Beyhive and beyond. "It was such a blur," the teen writes on her blog. "i just remember her bending down to me and my friend and I just turned for the photo and wowoowow! It was the best moment ever, like she posed it's crazy! I wasn't even expecting her to look at my phone or notice me in the crowd."

But what appears at first to be a legitimate photobomb turns out to be just the Greatest Selfie Ever (Beyonce Edition)!

Valentina sets the record straight on her Tumblr: "Okay so as most of the people that have recently followed me I have been the girl that got her selfie "photobombed" by Beyonce when in fact i asked her for the photo so she posed and smiled as the perfect person she is! Just thought I'd clear the air haha."

The photo is so great that it doesn't matter if it was really a photobomb or not -- not even to Beyonce, who posted a screenshot of it on her Facebook page!
