When Tammin Sursok announced her pregnancy, many fans questioned whether or not this meant Jenna would leave Rosewood for good. But don't freak out, Pretty Little Liars fans! The the mom-to-be says there's nothing to worry about. 

"Don't worry! Still shooting #pll," Tammin tweeted. "I wouldn't let you down!" 

As much grief as Jenna has given our Little Liars, we're excited to see more of her in Season 4. After all, we have so many questions! What is the "B" Team, and are they working against Red Coat or for her? Not to mention, who is that mystery guy accompanying Jenna to the funeral in the Season 4 premiere

We previously reported that Wyatt Nash will be playing Nigel, who is “savvy, charming and confident.” But watch out, Rosewood ladies! This one “may have a darker side” that is not immediately apparent, which means he's perfect for Jenna. Nigel will first appear in Season 4, Episode 1: “A is For A-L-I-V-E,” but will pop up again in Season 4, Episode 7: “Crash and Burn, Girl.” We're curious to see how he's connected to Jenna and the "B" Team. 

Meanwhile, we can all breathe a sigh of relief in knowing that Tammin isn't leaving PLL anytime soon. We suspect Jenna is going to be carrying a lot of bags (to hide Tammin's growing bump!) in Season 4.
