After being hospitalised and getting the Twitterverse and friends into a tizz over her health, Selena Gomez is already back at work and assuring her fans that she's alright!

According to contactmusic.com, Selena cancelled a concert performance on Friday following her health scare, but rescheduled the show for yesterday afternoon where she told her fans: "If you guys came on Friday, I'm so sorry that I couldn't be here... I love you guys very much."

Selena added: "I was just very malnourished... low on iron and exhausted."

We think it's time for a break, but we're so glad that she's better.
