We aren't sure if it's because she just worked out or it's the pregnancy bliss, but Ashlee Simpson was glowing when she stepped out with hubby Evan Ross.

The happy couple were hot and sweaty after a trip to a Hollywood gym on Thursday. Looks like the pregnant celeb, who already has six-year-old son named Bronx Mowgli with ex Pete Wentz, is trying to stay in shape while she's expecting.

For the workout, Ashlee donned a tank top with cleverly inscribed with the phrase, "Love Child."

The parents-to-be were married at the Diana Ross' home in Greenwich, Connecticut in August. Shortly after, Ashlee found out she was expecting on Thanksgiving Day.

The 30-year-old is due to welcome her first daughter in the summer.
