She was already number one in our hearts, but now Selena Gomez rests comfortably atop the charts, too!
Her AH-Mazingly infectious single Come & Get It is the most popular cut in all of the land and — believe it or not — it's the first time she's actually ever had a number one song!!!
The 20-year-old super-starlet was soooo ecstatic over her victory that she tweeted out a shaking, shivering, quivering, triple-adorbsiez video message for all her fans to enjoy!!!
When you're reh-eh-eh-eh-eady come and get Selenita's personal "thank you"…AFTER THE JUMP!!!
