LOS ANGELES, Aug. 12 (UPI) -- "Dirrty" singer Christina Aguilera shared a topless photo Tuesday on Instagram.
The 34-year-old recording artist stripped down to nothing but pink underwear just shy of a year after welcoming daughter Summer Rain with fiancé Matthew Rutler. Summer will turn one year old Aug. 16.
"Just so you know with me, it's all real, all the time," she captioned the selfie. "Felt like it was time to start sharing some personal stuff with you guys... And it's only the beginning. Night night. X."
Aguilera followed up by posting a feminized version of the Seneca quote, "He who is brave is free." The star shared the topless photo hours after Kim Kardashian posted a nude selfie to prove she is carrying her second child by Kanye West.
Aguilera and Rutler have been together since 2010, and the singer is also mother to seven-year-old son Max Liron with ex-husband Jordan Bratman. She last released Lotus in November 2012, and has yet to return to The Voice following Summer's birth.
