Christina Aguilera becomes singing teacher

Christina Aguilera has signed up with San Francisco based MasterClass to become an online singing teacher.

The $90 lesson includes video lessons, interactive exercises, learning materials, and workbooks.

Included in the Aguilera class:

*10-25 video lessons from the instructor (approx. 2-5 hours of video)

*Interactive exercises: for example, in Dustin Hoffman's MasterClass students can be matched with other students to practice scenes from the class, and then upload videos for feedback from other students (and sometimes even Dustin himself!)

*Learning materials: workbooks and class materials like excerpts from James Patterson's first drafts

*Lifetime access, with classes that never expire

*Learning materials and workbooks

*Accessible from any device

"I'm excited MasterClass has given me the opportunity to truly share all I have learned about my craft with the world. Coaching in this capacity not only gives me a chance to connect with my fans but lets me explore one of my true passions," said Christina Aguilera.

Other MasterClass teachers include Dustin Hoffman (acting), Serena Williams (tennis) and James Patterson (writing). Upcoming classes include Usher (performance), Annie Leibovitz (photography) and more to follow.

MasterClass, a San Francisco-based company which launched May 12, 2015, is an online education platform. It was co-founded by David Rogier and Aaron Rasmussen.

"Christina has one of the greatest voices of our generation. Not only that, but she truly wanted to teach! We're lucky to have her on board and can't wait to see what she has in store for students," said Co-Founder and CEO David Rogier.

Christina Aguilera will film her class this month. It should be available in the next couple of months.
