Has Ashlee Simpson caught baby fever?

The singer, who became an aunt earlier this month, recently brought home a kind of baby of her own – a white French bulldog puppy.

Simpson was spotted Saturday holding tight to her new dog while catching a flight out of Los Angeles International Airport. The puppy stayed wrapped in a plush blue blanket as Simpson made her way past paparazzi.

Already a mom to son Bronx, 3, Simpson, 27, shared a photo of her two babies lying around together last week.

“BX and our new puppy snuggle fest!” she Tweeted.
