Demi Lovato had a very busy 2014 between touring, collaborating with other artists such as Nick Jonas and so much more, but she always has time to thank her fans.

Last Wednesday, the singer tweeted her Lovatics with the link to the music video for Nightingale and a sweet, appreciative message.

"Thank you all so much for the most amazing year yet! My Lovatics are truly the best," Lovato shared in the tweet.

Her music video is in black and white for Nightingale, which is on her fourth studio album Demi that released last May.

The video stars Lovato's fans, which is a beautiful gift to them since she is so thankful to have their support. It's filled with plenty of behind-the-scenes footage, including some from her various performances, her interactions with fans and much more.

The music video definitely pulls at heartstrings as some fans are seen crying and Lovato sometimes appears lonely when shots of her traveling are shown.

One really sweet moment in the video is when Lovato reunites with her boyfriend Wilmer Valderrama and they share a smooch.

The Nightingale singer shared another sweet treat with her fans Monday, which happened to be a little bit more teasing since she tweeted, "SO excited to share I'm teaming up with ‪@HasbroNews and ‪#Twister in 2015!"
