Ashlee Simpson won’t give up being sexy just because she’s pregnant. She donned a bikini during a recent trip to Maui. She and hubby Evan Ross were spotted lounging in the sun during their babymoon.

It won’t be long before Ashlee Simpson and Evan Ross welcome their baby girl into the world. Simpson already has a little boy–Bronx–from her marriage to Pete Wentz. She was very excited about learning the gender of their baby. They found out in February that they will be blessed with a little girl.

“I like to know–I want to do the nursery,” Jessica Simpson’s younger sister said during a recent interview with Us Weekly. “I’m just excited for the new addition.”

Son Bronx is very excited about the new baby’s impending birth.

“He wanted to have a sister, so he’s really excited!” Ashlee Simpson said.

Ashlee Simpson and Evan Ross tied the knot back in August of 2014. They married at the home of Evan’s mom in Connecticut. His mother is famed singer Diana Ross.

It is always interesting to learn what celebrities choose to name their children–and people are likely wondering what Ashlee Simpson and Evan Ross will name their daughter. Hopefully it will be a name she won’t mind having as a child, and that she can easily transition into adulthood without any embarrassment.

Kudos to Ashlee Simpson and Evan Ross for getting away on this babymoon–and to Ashlee for sexing things up in her bikini–before baby makes four.
