On her own birthday, Selena Gomez turns it around on us and gives us the gift: a music video for her single “Birthday”!

Chelsea Briggs gives you a look in today’s Hollywire Hot Minute!

We may always wonder what it is like to be a teen sensation, but when it comes to how they would celebrate their 21st birthday, wonder no more! SelGo released a video of her partying with all of her close friends while singing and dancing to the super catchy new single "Birthday" from her upcoming album Stars Dance!

In the description for the video, Selena even takes time to thank all her Selenators saying: “I wanted to celebrate my 21st Birthday with all of you, so we made this video for us all to celebrate to. Thank you for all the love and support you have shown and continue to show me. I love you all so much!!”

Sel is being pretty generous and it makes us love her even more, but since it is her 21st birthday we’ve got to look back at how it all started. How? Disney Channel Selena, duh!
