Christina Aguilera giving online singing lessons

Christina Aguilera is teaching wannabe singers how to improve their voice in an online course.

The Dirrty singer has partnered with MasterClass, an online education site, to give tutorials on how to improve vocal range, control breathing and warm up the voice. She'll also show off her vocal techniques by breaking down her biggest hits.

The instructional singing program is broken down into 20 video classes, and follows on from Kevin Spacey's acting course, Usher's performance tutorial and Serena Williams' online tennis class.

Explaining how she got on board with the project, Christina tells The Hollywood Reporter, "I met the people involved and I really felt confident that this is such a positive and great thing to do to allow people to have access to. It’s a class or courses being taught by the greats in what they do, in the fields they’ve been successful in.

"You’re getting courses with best of the best in the comfort of wherever you want to learn from - in your own space and on your own time. Allowing yourself the time to explore your passion is amazing. And at a great price. My experience with The Voice has also helped lead me to this place."

She admits she would love to take Kevin's acting course and is always on the lookout for another acting project following roles in Burlesque and TV show Nashville, but finishing her next album takes priority.

Of the record, she remained tight lipped: "I can’t say much about it yet because I want to wait until it’s good and ready. I am working on it and will be ready when it can be the authentic masterpiece that it deserves to be. But later this year, most likely."
