In celebration of the new episode of Jersey Shore: Family Vacation airing tonight, Deena Cortese's oldest son, CJ, wished fans a "Happy Jerzday" on Instagram. Deena posted the adorable video of her two-year-old son on Instagram early Thursday afternoon. She also included the teaser clip for the new episode in the post as well. Fans can't get over how cute CJ is.

Jersey Shore: Family Vacation just returned last week and fans are already saying the new season is better than the last. Now that the seemingly never-ending wedding drama has finally come to an end, viewers are seeing different storylines unfold amongst the cast. In just the first episode alone, fans were introduced to Ronnie Ortiz-Magro's new girlfriend, Saffire Matos, watched as Vinny Guadagnino went house hunting in Los Angeles, and learned of the martial issues between Angelina Pivarnick and Chris Larangeira.

With the second episode of the new season just hours away, Deena's oldest son CJ, who recently became a big brother, joined in on the excitement. Deena recorded her son in the living room of their home as he exclaimed, "Happy Jerzday" for a video she later posted to Instagram. Deena chimed in, using her loving mom voice, cheering, "Yay! Happy Jerzday," before CJ repeated it yet again. The energetic two year old was both jerzday and summer-ready in a black and white pair of shorts and a tank top that read, "No one likes a shady beach."  Watch the adorable video below:

While fans were just as excited for the new episode as CJ, they also could not get over how cute the video of CJ was. The comment section of the post flooded with heart-eye emojis and kind words of praise and admiration. One user wrote, "You have the cutest kid evaaaah."  Another informed Deena that CJ is a "little rising star." Perhaps he will steal the show if the roomies' kids ever do have a spin-off show of their own. Others could not help but acknowledge how fitting his shirt was for a jerzday celebration. Laughing at his shirt, one fan jokingly wrote, "Ang, that's for you!"

In the post, Deena includes the teaser clip for tonight's new episode. The clip starts off with Deena yelling from a car "Happy Sober-versary," as the family comes together to celebrate Mike "The Situation" Sorrentino's major life milestone of being five years sober. The clip then teases the "biggest surprise yet" as Nicole "Snooki" Polizzi shocks both fans and the roomies with her long-awaited return to the show. In a recent interview, Deena revealed she and the rest of the roomies did not even know that Nicole would be returning to filming with them.
