Before the couple took their relationship to the next level, PEOPLE spoke with celebrity astrologer Kyle Thomas, who analyzed both Swift and Kelce's natal charts to predict their overall compatibility. First and foremost, he said it was important to note that Kelce was born about two months prior to Swift.
Swift is a Sagittarius Sun with a Cancer Moon, while Kelce is a Libra Sun with a Sagittarius Moon. "This means that they will share many key astrological placements, particularly with the outer planets," said Thomas.
"Factoring in romance and intimacy, intellectual rapport and communication, career and financial support, friendship, domestic union and true long-term synergy," Thomas told PEOPLE exclusively, he gave Swift and Kelce "a 9 out of 10" when it comes to "their overall compatibility."
Here's a deep dive into Swift and Kelce's compatibility, based on Thomas' readings.
Thomas explained to PEOPLE the importance of birth dates, particularly pointing out the closeness between the days Swift and Kelce were born, Dec. 13, 1989, and Oct. 5, 1989, respectively. As a result, the pair share "many key astrological placements."
Both Swift and Kelce possess Pluto in Scorpio, which Thomas said "brings them great passion and a desire for transformation." He added that they both possess a Capricorn stellium, which "aids them in breaking down and rebuilding core structures in their lives and in the world at large."
They both have Jupiter in Cancer, which "is one of the luckiest positions for this planet to be," according to Thomas, adding that it "grants them a 'golden touch' to whatever they do, especially when they lead with their hearts."
Lastly, Thomas said both Swift and Kelce carry a North Node in Aquarius, meaning "they carry a great desire to break out of the box, connect to community, and pursue their aspirations, as well as work for the greater good."
Furthermore, Thomas said they both carry South Nodes in Leo. This means that they are each "naturally drawn to all things that Leo rules," citing "romance, passion, entertainment, the arts and sports" as examples.
Based on these placements, Thomas said the overall assessment reveals that both Swift and Kelce "possess a karmic entanglement that makes them feel familiar to one another." He added, "They can easily be seen as an ideal couple for their generation, somewhat of a King and a Queen of an era."
When it comes to Swift and Kelce's romantic compatibility, Thomas said that "this is a couple that has profound sparks!" In fact, he added that they are "the perfect union of romance, chemistry and attraction as they share one of the rarest planetary dances."
Thomas said that Swift's Mars ("the planet of sex and desire") and Kelce's Venus ("the planet of affection and romance") are "exactly in the same place," indicating that "they perfectly complement" each other. "There is high romantic attraction and an ability to commit and compromise," he added.
In addition, Thomas said that there's "tons of flirtation and charm between" their signs which can bring them "expansive joy" and a desire to "rush in." However, he warned them to avoid "diving in too fast as this could leave their rapport like a whirlwind."
Thomas said that Swift's Sun is in "close enough conjunction" with Kelce's Moon, revealing again that this is "one of the best aspects of synergy a couple can have" as it can create a connection of camaraderie filled with "warmth, pleasurable exchanges and strong affinity."
Swift's Neptune ("the planet of imagination") also aligns with Kelce's Sun, Mars and Jupiter, said Thomas, "bringing compassion, a dreamy quality to their exchanges."
He noted again, though, that "the key is to not get too lost in a fog of fantasy and to truly focus on being open and sensitive."
Swift and Kelce's signs have "so many alignments that favor active communication and a desire to learn from one another," according to Thomas, who added that the stars "can open up one another's minds" with their Mercury, Jupiter and Mars interacting.
"This can be a lively and exhilarating connection, but there could be times when tempers will flare as they can both get fired up and will need to balance this," he continued. "At their best, they can be particularly enriching to each other, but real freedom and honesty will be paramount."
Swift's Mercury ("the planet of communication and the mind") is united with Kelce's Saturn, which Thomas said brings them "stability and balance." Also combined with Kelce's Neptune, he added that this brings them "encouragement and the ability to develop a telepathic rapport."
However, Thomas noted that Kelce's Uranus ("the planet of revolution and chaos") in comparison to Swift's Moon ("ruling her emotions and soul") could put forth an "on again-off again quality to their rapport if they are not aware of these ebbs and flows."
Fortunately, Thomas said that the couple "can still broaden one another's perspectives a great deal."
When it comes to Swift and Kelce's career and finances based on their signs, Thomas said, "they instantly amplify one another significantly." He pointed out that both of their Jupiters are opposite each other's Saturns, signifying "excellent long-term growth, as well as the ability to forge further wealth and glory as a power couple."
He continued: "Stability is something the two could actively work toward ultimately aiding one another in world-building."
If you're wondering why Swift and Kelce were drawn together at this point in time, Thomas pointed once again to astrology. He noted that Venus ("the planet of love and beauty") spent a "great deal of time in the zodiac sign of Leo in the summer and autumn of 2023."
In fact, Thomas said that at the time of their initial romance, Venus had been going back and forth over their South Nodes in Leo -- which he said represents "karma, past lives and what one easily attracts in life from previous lives and experiences."
In this regard, Thomas believes that Swift and Kelce "have a past-life connection." However, he said, "it was one that they may not have initially realized from their first interactions or moments of meetings."
At the time of going public with their romance in September 2023, he noted that Venus was at 20 degrees of Leo, which was directly between both of their South Nodes. "With Venus waking their connection up," he said,"[Swift] has drawn them together now."
"Whether they are to stay together for a long time or not -- and I do think they have a lot working in their favor -- this was meant to happen and will be a destined pivot point in both of their lives," Thomas concluded.
