Katy Perry showed just how amused she was at a viral video featuring a baby getting excited about her song “Dark Horse,” even joking about offering up her babysitting services.

She tweeted the video to her more than 55 million Twitter followers, and wrote, “Available for babysitting at 10 dollars an hour & 4 Oreos.”

The video features an adorable but fussy baby sitting in a car seat. Once Perry’s “Dark Horse” plays through the speakers, though, everything changes. The baby’s frowning face turns into a look of pure delight.

The video now has over 1 million views on YouTube, proving Perry isn’t the only one who enjoyed this gem.

This tiny Katy Perry fan has hardly been the first to steal our hearts when it comes to getting excited about music – even stopping some fits along the way.

Remember the baby who would only eat when watching a music video for Psy’s “Gangnam Style”? Or four years ago when that diaper-wearing baby danced to Beyonce’s “Single Ladies”?
