The Jersey Shore castmates are around the same age, but most have different zodiac signs, and their Sun signs may ultimately play a role in the drama that crops up on the show. While some astrologers will point to an entire birth chart to provide a full picture of a personality, a lot can be discovered about someone's character by simply looking at their Sun sign. The sun sign is the most recognizable sign and the one that would stand out the most in a public setting, like reality TV.

The cast of Jersey Shore all play their roles on the show, creating drama and resolving it with one another, and a lot of that behavior can be predicted from their signs. Long-time viewers know that each season of Jersey Shore, which had an MTV special, consists of outbursts, drama, and hookups. However, some roommates tend to be more involved in the drama than others. While many of the castmates are stirring things up and getting into fights, others stand by and only jump in when necessary. All of this behavior is somewhat predictable if you look at each cast member's astrological Sun signs.

Jersey Shore's Mike, Angelina, & Pauly Are Compassionate Cancers

Jersey Shore's Mike, Angelina, and Pauly

Three castmates were born in the summer, and they all share the same zodiac sign. Angelina Pivarnick, Mike "The Situation" Sorrentino, and Paul DelVecchio Jr. are Cancers. Angelina's birthday is June 26, while Mike and Pauly D are just a day apart, born on July 4 and 5, respectively. Cancers have many great traits. They are compassionate and caring spirits, and they are loyal. While Mike and Pauly tend to portray these characteristics more than Angelina, who's a great addition to Jersey Shore, she still fits the Cancer mold. Angelina was very concerned about her now ex-husband, Chris Larangeira's, feeling after the drama went down at their 2019 wedding. While she may have found the infamous bridesmaids' speech to be funny at first, once she realized that her husband was offended, she cared more about his feelings than her own. The downsides of Cancer are moodiness and vindictiveness.

Jersey Shore's Jenni & Sammi Are The Creative Pisces

Jersey Shore's JWoww and Sammi

Sammi "Sweetheart" Giancola and Jenni "JWoww" Farley may have bumped heads over the years, but they do have one thing in common, they have a creative side. Sammi was born on March 14, while JWoww was born on February 27, which makes them both Pisces Sun signs. This may be why they are both motivated to be so creative in the business world. Sammi, who blocked Nicole "Snooki" Polizzi, has her own company, Sweetheart Styles, while JWoww started her own mother-daughter boutique online.

Jersey Shore's Snooki & Ronnie Are Free-Spirited Sagittarians

Jersey Shore's Ronnie and Snooki

Spiral meatball squad Snooki and Ronnie Magro-Ortiz were both born under the sign of Sagittarius. Nicole's birthday is November 23, while Ronnie's is December 4. Sagittarians are known for being the life of the party. On the other hand, Sagittarians can also be quite blunt and sometimes come off rude. Ronnie and Nicole have found themselves in some confrontations over the years due to their fearlessness when it comes to speaking their minds. Sagittarians are Fire signs who sometimes want a little payback when they feel wronged. While this doesn't typically apply to Nicole, Ronnie was guilty of seeking revenge in the past.

Jersey Shore's Vinny Is A Loyal Scorpio

Vinny Guadagnino's birthday is November 11, making him a Scorpio. Scorpios are known for being loyal, which fits Vinny, even when he was looking for love on Double Shot at Love season 3. Vinny, who was defended by DWTS fans, has been loyal in his friendship with Pauly D and the rest of his roommates. Scorpios also tend to be more on the calm side, which explains a lot about Vinny's personality, which his roommates tend to mock him for.

Jersey Shore's Deena Is The Responsible Capricorn

Although she has had her fair share of wild moments, Jersey Shore star Deena Nicole Buckner often acts like the mom of the group, which may be because of her zodiac sign. Born on January 12, Deena is a Capricorn, and they tend to be more on the responsible side. While the downfall of this sign is a guarded nature, Deena does not seem to have this trait. When she first joined the Jersey Shore season 3 cast, she came in full force, letting her walls down and, accidentally, her clothes as well. Sometimes, Capricorns have a difficult time forgiving others, which Deena proved in her reaction to Angelina's past behavior. Deena also didn't invite Ronnie to her wedding because he didn't reach out after her father passed away. She also had a hard time forgiving Angelina after the wedding fallout in a past season of Jersey Shore: Family Vacation.
