Holly Madison looked angelic in white as she cradled her baby bump at the launch of her "Lucky Pet Products!"

On Tuesday, "The Girls Next Door" star promoted her new pet line in Las Vegas … with the help of some adorable furry friends.

“So excited to launch my pet line, Lucky Pet Products, at Superzoo (Mandalay Bay) today! I’ll be there 2pm-come say hi! Xo,” Holly tweeted.

The 31-year-old, who is expecting her first child with Pasquale Rotella, was spotted earlier this week for the first time baring her baby bump in a pink bikini.

The Playboy bunny is also sporting a darker ‘do and a more natural look – maybe because she’s got that pregnancy glow!
