Christina Aguilera has reportedly teamed up with Australian singer Sia for her upcoming album. Sia lavished praises on the ‘Beautiful’ singer, saying, "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," Sia added.
