In the new 'Allegiant' trailer, we see Theo James and Shailene Woodley getting naked with each other in the shower. This makes fans await 'Allegiant' opening with even more fervor, in hopes of witnessing one of the most palpable onscreen romance of Theo James and Shailene Woodley.

Let's hope that Theo's girlfriend Ruth Kearney isn't too worried that he will have a wandering heart.

According to MTV, "Soundtracked by Sigur Ros' Jonsi, the clip feels mellow but foreboding, as we see Four (Theo James) bare it all for Tris, before warning her that faction-less life may not be all they dreamed it'd be. The trailer also offers our first look at Jeff Daniels, who joins the cast for the final two films of the series, as well as returning players Miles Teller, Ansel Elgort, Zoe Kravitz, Naomi Watts, Octavia Spencer and Maggie Q."

About half way through 'Allegiant' trailer, the fans get to see Theo James and Shailene Woodley totally strip down to reveal themselves in front of each other. Things are heating up for the final round of 'Divergent' series!

To move on, Shailene Woodley finally let go of Theo James to take the next step to advance her career. This time, she will be joined by the Hollywood hottie Alexander Skarsgard in a new HBO series.

According to Newser, "Shailene Woodley and Alexander Skarsgard are part of a new HBO project, "Big Little Lies." They join previously announced stars Reese Witherspoon and Nicole Kidman, who also are executive producers for the limited series."

With Alexander Skarsgard taking place of Theo James, Shailene Woodley may be able to focus on her relationship with her boyfriend.

Shailene Woodley will miss Theo James once "Allegiant" movie release date comes and goes, but with Alexander Skarsgard to look forward to, this goodbye might not feel so painful.

"Allegiant" movie release date is set for March 18, 2016 and is projected to be a blockbuster of this spring.

Shay and Theo are known for their on screen chemistry, which inspired dating rumors despite the fact that he is going steady with Ruth Kearney.
