It’s back to diaper duty for Paulina Rubio…

The 44-year-old Mexican singer Gerardo Bazúa has given birth to her second child, a baby boy born on March 5 in Miami.

It’s Rubio’s child with Mexican singer Gerardo Bazúa, a former contestant from her team on La Voz… México.

This is Rubio’s second child. Her first, Andrea Nicolás, 5, is from her marriage to Nicolás Vallejo. The couple divorced in 2013.

Rubio met Bazúa in 2013 when she was a coach on La Voz… Mexico. Bazúa has two children from a previous marriage.

Rubio hid her pregnancy well for several months. But in December, when she performed at Miami’s Grand Slam Party Latino, she was showing a baby bump.

No word yet on the baby’s name.
