According to new research by Tarotoo, some of Hollywood’s most iconic couples are written in the stars — but not necessarily in harmony.

The tarot and astrology platform analyzed celebrity birth dates, zodiac signs, relationship lengths, and compatibility scores to reveal which pairs defy the odds when it comes to cosmic chemistry.

Nearly 70% of Americans check zodiac compatibility when starting a new relationship, but these famous duos prove that love can thrive even when the stars say otherwise.

Hollywood’s least compatible couple: Matthew McConaughey and Camila Alves (9%)

The Scorpio-Aquarius pairing of Matthew McConaughey and Camila Alves ranks as the most astrologically mismatched couple in America, with just 9% compatibility. Yet the couple has maintained a strong marriage for over 13 years since tying the knot in 2012.

Danny Moder and Julia Roberts: same signs, same odds

Tying for first place with an identical 9% match, Julia Roberts and Danny Moder also fall under the Aquarius-Scorpio axis. Despite their cosmic mismatch, their marriage has lasted an impressive 23 years.

Jay-Z and Beyoncé: 13% compatible, 100% iconic

Sagittarius and Virgo aren’t supposed to mix — one thrives on freedom, the other on structure — yet Jay-Z and Beyoncé have managed to harmonize fire and earth for 17 years.

Leo and Capricorn couples defying astrology

Both Viola Davis and Julius Tennon, and Barack and Michelle Obama share the same cosmic combo — Leo and Capricorn — and the same 27% compatibility score. The Obamas, in particular, have sustained a 33-year marriage, proving that long-term love often transcends astrology.

Timothée Chalamet and Kylie Jenner: new couple, same zodiac clash

Kylie Jenner and Timothée Chalamet also share the Leo-Capricorn pairing, with the same low 27% compatibility as the Obamas — but only two years into their relationship. In contrast, Taylor Swift and Travis Kelce (Libra-Sagittarius) boast a sky-high 91% match, making them the cosmic opposite of Chalamet and Jenner.

George and Amal Clooney: Taurus meets Aquarius (28%)

Grounded Taurus and visionary Aquarius rarely find easy balance, but the Clooneys’ 11-year marriage proves that stability and innovation can coexist — at least off paper.

John Legend and Chrissy Teigen: Capricorn meets Sagittarius (33%)

Despite differing values — Capricorn’s discipline versus Sagittarius’s spontaneity — this pair has made it work for more than a decade.

Swizz Beatz and Alicia Keys: Virgo and Aquarius (36%)

With 36% compatibility, this couple’s 15-year marriage challenges the stereotype that air and earth signs can’t connect.

Serena Williams and Alexis Ohanian: Taurus and Libra (37%)

The most compatible couple on the list, yet still below average at 37%, Taurus and Libra share a love of beauty and balance that has fueled their eight-year marriage.

“Some astrologically incompatible relationships show that connection goes deeper than sun signs,” a Tarotoo spokesperson explains. “When we look at successful couples, we need to consider full birth charts — including moon and rising signs — which reveal emotional and spiritual compatibility that sun signs alone can’t capture.”

In short: Love isn’t always written in the stars — sometimes, it’s rewritten by the people who dare to prove astrology wrong.
