Historical sci-fi series Outlander has already become a hit.

The much-awaited wedding episode of the hit show Outlander is here.

Outlander season one episode seven, aptly titled The Wedding, will show Jamie and Claire's marriage. The latest episode synopsis teases some spoilers about the union and looks like Claire is not entirely happy about the union.

The episode's official synopsis reads: "Claire and Jamie are thrown together in marriage, but as their emotional and physical relationship unfolds, deeper feelings arise. Claire is ultimately torn between two men in two very different times."

Sounds like viewers will get to see Claire and Jamie's physical relationship start on their wedding night.

Check out this promotional video showing Claire getting a bit nervous on her wedding night:

The upcoming episode might further complicate matters of the heart for Claire. Even though she cares about Jamie, she wants to return to her husband, Frank Randall, in the 1940s. She, however, cannot share her dilemma with Jamie as she's told everyone that her husband is dead.

"We're very excited for people to see the wedding episode," Caitriona Balfe, who plays Claire, told Access Hollywood. "I think it's gonna live up to people's expectations," she added.

Outlander episode seven The Wedding will air tonight at 9pm ET (5pm GMT) on Starz.
