Tamera Mowry is ready to take a walk on the wild side!

Tagging along with her husband of 15 months, Fox News correspondent Adam Housley, when he's sent to South Africa on assignment, the Tia & Tamera star, 33, can't wait to explore their new surroundings in Cape Town -- until, of course, she comes face to face with some new neighbors: Lions.

"I'm really scared!" the pregnant reality star yelps during a guided safari tour at the Aquila Wildlife Reserve with her cousin, Jerome. As a pack of lions gets closer and one shows his teeth, Mowry's tour guide admits that the animals can sense her fear.

"My life just flashed before my eyes," Mowry -- expecting a son with Housley this fall -- recalled after venturing through the safari unharmed. "I thought he was just going to pounce on the truck and eat us."

Watch more of Mowry's vacation antics in the clip above before the full episode of Tia & Tamera airs Monday at 8 p.m. (EST) on STYLE.
