Christina Aguilera likes Australian pop singer Sia so much that they've teamed up for Christina's next album!And apparently it's a little much for Miss Sia to take in.
"I definitely pooped my pants when she first sang out loud in the room with us," 33 year-old Sia posted in her blog.
"I love her. She's a nice person. A good person. An awesome mama. An incredible talent. Incredibly professional. A feminist. A rad role model for women who want to believe we can have it all, do it all."
