Baby no. 2 on way for Chrissy Teigen, John Legend

Model and TV host Chrissy Teigen is expecting her second child with husband John Legend.

Teigen's one-year-old daughter Luna Simone Stephen helped her mom reveal the good news on social media.

The 31-year-old took to Instagram to share an adorable video of Luna playing with her baby bump.

"Luna, what's in here?" Teigen asked, as Luna replied, "Baby!" while rubbing her mama's belly.

"it's john's!" Teigen cheekily wrote in the caption of her video.

The couple, who tied the knot back in 2013, welcomed their first in April 2016.
