Is it too early to call this the wedding of the year? Yes, the cat has long ago been let out of the bag. Leonard and Penny are finally tying the knot in the The Big Bang Theory Season 9 premiere episode The Matrimony Momentum. And lt looks like Leonard's having a bit of a problem carrying Penny across the threshold. CBS has released the first trailer, and it looks like the couple's nuptials are very barebones, understated and definitely no frills as they enjoy their short honeymoon in Las Vegas.

This latest sneak peek debuted last night during the premiere episode of Late Show with Stephen Colbert. We get only a fleeting glimpse of Penny (Kaley Cuoco) in her wedding attire as she prepares for her very short walk down the isle with Leonard (Johnny Galecki). The rest of The Big Bang gang are watching everything go down via satellite. After the 'I Do's, the longtime couple head back to their hotel room, where it appears they'll have quite the awkward wedding night in true Leonard and Penny fashion.

The wedding date is set for September 21. In The Matrimony Momentum, after driving to Vegas to get married, Penny struggles with Leonard's confession that he kissed another girl. Also in this same episode Sheldon doesn't know how to act after Amy pushes pause on their relationship. You may remember that at the end of The Big Bang Theory Season 8, it looked as though Shelly (Jim Parsons) was gearing up for a possible future wedding of his own. Plans that he put on indefinite hold.

A big wedding isn't the only thing being planned for The Big Bang Theory Season 9, Leonard and Sheldon will be awakened by the force in true Big Bang Theory fashion. Star Wars: The Force Awakens will wreck havoc on the lives of Dr. Cooper and Dr. Hofstadter in a big way with an episode that completely revolves around the release of the first Star Wars movie in ten years. Sheldon, Leonard, Howard and Raj have all been obsessed with the Star Wars franchise since the show first premiered way back in 2007. And their love for the franchise will continue in the upcoming episodes.

While the wedding we see teased in this latest trailer is a pretty big deal for these two long-suffering love birds, tying the knot is just the beginning of a much larger story. Season 8 left off with a nail-biting cliffhanger which saw Leonard revealing to Penny that he'd cheated on her during his North Sea expedition. They were on their way to Las Vegas for a drive-through wedding, one that will still take place. Though not without complications. Leonard and Penny's honeymoon will be stalled, partly by the appearance of Leonard's fling, played by Melissa Tang.

While the wedding will take place in the first episode of The Big Bang Theory's new season, Leonard's other woman doesn't appear on the scene until episode 2. And it's going to get ugly. So far, we have not yet heard how Leonard and Penny's marriage will affect Sheldon, and in turn, his relationship with Amy. We'll all have to wait and see how that plays out when The Big Bang Theory Season 9 returns on CBS. Take a look at the trailer, and be sure to set your DVR for September 21. Though, if you miss it. we're sure you'll have no problem catching it in syndication.
