Lex Murphy is going to be a mom!

Ariana Richards, who portrayed the young gal who's terrorized by a T.rex in 1993's Jurassic Park, has announced she and her husband, Mark Bolton, are expecting their first child.

The 35-year-old artist confirmed the news to People. "My husband and I are thrilled,” the pregnant former child star says. “This is really a wonderful moment for us. It’s super exciting.”

Ariana also tells the outlet she would have loved to attend the Jurassic World premiere in LA earlier this week, but she decided to stay put in South Africa (where she currently lives) to focus on her pregnancy.

“My experience working on Jurassic, it was so groundbreaking,” she explains. “It’s so fun to be part of something that touched the culture in such a big way and that brings people so much joy.”
