As you may know, Pretty Little Liars star Tammin Sursok (Jenna Marshall) is about a month away from welcoming her first child into the world and she is making pregnancy look fun. Earlier this month, Tammin tweeted about having cupcakes for lunch. What is she up to this week?

An epic hike! “8 months pregnant hiking the canyon!!! Strong, fit, healthy!! @seanmcewen1,” Tammin wrote on Instagram earlier today at her husband, Sean McEwen, the father-to-be. The pic that accompanies the tweet shows a gorgeous Tammin with her hands raised in triumph at what looks like the bottom of the canyon. In the snapshot, you can barely even tell the Aussie actress is pregnant, let alone eight months along!

But Tammin’s not trying to hide her baby bump. The PLLer showed off her pregnant bod in a black bikini during a beach trip with Sean earlier this month, as well as in photos of the family’s recent vacation in Croatia. These two make good looking parents-to-be.

The actress had to hide her baby bump in scenes she filmed for PLL’s summer season, but there’s no word yet on whether she will have to do the same for the winter season, which is filming now. As much as we want to see Jenna again soon, we hope Tammin has plenty of time to spend with her baby!
