Evan Ross doted on pregnant wife, Ashlee Simpson, after hitting the gym in Los Angeles last Tuesday.

The "Hunger Games" actor was snapped assisting the "Pieces of Me" singer as she made her way down the stairs outside of the gym.

The pregnant Ashlee Simpson has been hitting the gym for light workouts to make sure she and the baby are going to be healthy.

"Ashlee showed off her growing belly in a tight black blouse and cropped black leggings which she teamed with matching Nike trainers," Daily Mail said. "She appeared to be make-up free, looking a bit flushed from her rigorous session, as her long blonde locks were swept back into a ponytail."

In November of last year, Evan Ross gushed over the pregnant Ashlee Simpson.

"It's the best thing ever. I actually want to get back to her, although I'm excited to be on the carpet - it's incredible," Ross, 26, told Us Weekly during the "Hunger Games: Mocking Jay Part 1" premiere in Los Angeles. "I wish she didn't leave but there's a lot going on here."

"I've been with her now for a while so it just feels right. I'm happy to say she's my wife," he added. "I would love to [have kids] as many as possible."

On her pregnancy, Ashlee Simpson said that it's going so well and the only complication is she's "just hungry all the time.

"I feel great. I, luckily, haven't been sick. It's been pretty laid-back. Nothing's been hard about it - I feel wonderful!" she told People, adding that she also had no problem when she was pregnant with Bronx.

Ashlee Simpson also credited Evan Ross for being so supportive.

"Massages, cooking - all of that! He's making me feel so special! I feel like the luckiest lady ever. I'm like, 'Thanks, babe!'" she said. "It's amazing. I love my husband, we have a beautiful family, I love his family ... It's wonderful."
