Expectant mama Ashlee Simpson was all smiles the Crayola Color Alive launch in New York City on Thursday (February 5). The radiant mom-to-be, 30, was joined by husband Evan Ross and her 6-year-old son Bronx.

While at the kid-friendly event, the singer-reality star revealed her baby’s gender.

“[It’s] A girl,” she revealed to E! News.

After the fun family outing, Simpson Instagrammed a group photo.

“Spent the afternoon with @Crayola for #ColorAlive Launch. Look what Bronx made! #spon #happytimes #familyfun,” she captioned the shot.

This will be the first child for Ashlee and her newlywed husband, 26, whom she wed on Aug. 30.

She co-parents Bronx with ex-husband, Fall Out Boy rocker Pete Wentz.
