Paulina Rubio and Demi Lovato reunited in Mexico City over the weekend at Lovato's concert, where the Mexican singer jumped onstage with her "little sister" to sing Cyndi Lauper's '80s anthem "Girls Just Want To Have Fun." 

"Thank you for inviting me. I love you little sister, see you soon," wrote Rubio on social media. The former X Factor judges rocked the Palacio de los Deportes stage, singing their hearts out, dancing and hugging each other.
