Vanderpump Rules season 4 could begin with a trip to Las Vegas for Scheana Marie's 30th birthday party.

Scheana Marie Returns To SUR Lounge, Reunites With Jax Taylor

Because Marie's 29th birthday party was featured on the first couple of episodes of Vanderpump Rules, fans have reason to believe production may start during tomorrow's party.

"Heading to vegas tomorrow with the crew !!! @scheanamarie birthday weekend!!! #Vegas," Jax Taylor wrote on Twitter on Tuesday afternoon. Hours later, he added a second tweet, which read, "Off to bed #Vegas in the morning with @twschwa @MusicKillsKate @CourtneyBerman #roadtrip."

Scheana Marie Shay Has Broken Another Tooth

Although Vanderpump Rules season 4 hasn't yet been confirmed, filming on Bravo reality shows typically begins around the same time each season, which means if the show has been renewed, production is due to start at any minute.

Before heading home from work on Tuesday evening, Marie and Katie Maloney, with whom Marie formed a friendship during season 3, enjoyed a date night with their respective partners, Mike Shay and Tom Schwartz.

"From work night to date night! @MusicKillsKate @SurRestaurant LOL," Marie told fans on Twitter.

During Vanderpump Rules season 3, Marie and Maloney, who were once on the outs, began spending time together and even after the show wrapped, the pair continued their friendship.

As for who else will be included in Marie's birthday event, that has yet to be revealed. However, if history repeats itself, the majority of the cast will be involved, and pictures are sure to be shared on social media.
