You guys, sadly we live in a world where celebrities fail to recognise other celebrities and it's just a bit heartbreaking.

During the week, Teen Wolf, Arrow and future Scream Queens babe Colton Haynes was living it up in Vegas and decided to treat himself to Britney Spears' concert.

During the show, Britney spotted a very cute Colton in the audience and wanted to bring him up on stage so she could dance with him during her "Freak show" segment. Except, she had no idea who he was.

“That was so much fun, oh my God. Thank you for coming up here and dancing with us,” Brit said to Colton after performing with him.

“What’s your name? Colton? Give it up for Colton everyone! You’re an amazing dancer, oh my goodness.”

Oh, and she also thought his booty was great.

"Wow, call me anytime,” she said as he left the stage. “Everyone’s so beautiful, and his ass!”
