Christina Aguilera Teases New Music on Instagram: 'Finishing Touches to My Heart'

Christina Aguilera is putting the "finishing touches" on her upcoming album!
The 36-year-old singer took to Instagram on Wednesday to tease new music with a black-and-white image of herself by a piano.
"Finishing touches to my heart ❤️ ?," Aguilera captioned the pic.

The mother of two released her last album, Lotus, in 2012, but has been working on her new record for quite a while. 
"I'm big on the marination process," she told ET in 2015. "I have to make sure the details are all there."
"I really value the creative process and the time it takes," she added. "I am working with some incredible new people that, even I'm surprised [to be working with], and then also re-joining with some dear friends of mine, collaborators [like] the beautiful Linda Perry."
And last February, Aguilera told ET that she was working on "multiple albums": "One being a follow-up to my debut Spanish album, [and] a few solo projects with some incredible producers."
Though the former Voice coach has been hard at work for the past few months, she partied it up in December with Kylie Jenner – who showed up to Aguilera's birthday bash in an epic Xtina costume.
