Tammin Sursok recently confirmed that she would be back on "Pretty Little Liars" season 7. In a new interview with Cosmopolitan, the actress teases the return of her character Jenna Marshall, which she claims will be "a big surprise" for the girls. "The girls haven't seen Jenna in a year and a half, so it's kind of a big surprise," she says.

Sursok is coy when describing what Jenna's return means for the show, only gushing, "She's definitely involved in a lot of exciting, tantalizing things that the viewers want answers for." And according to Sursok, Jenna's still as mysterious as she has been before, adding, "We still tread the line of, 'Is she blind? Is she not blind?' She's gonna come back with some gusto, and I'm in most of the season, so it's pretty exciting."

While Sursok remains mum about her character's story arc, she hinted earlier this month that Jenna's return would bring trouble for the Liars. "SHE'S BACK B***HES!!!!! #jenna #jennaisback #missme #pll #prettylittleliars #justwait #beafraid @prettylittleliars," she posted on Instagram when announcing her comeback.

"Pretty Little Liars" season 7 premieres Tuesday, June 21 at 8/7c on Freeform. Executive producer/showrunner I. Marlene King recently said there would be a wedding in the new and potentially final season.
