Twinning has been one of the biggest fashion trends over the years. Interestingly, this doesn't only apply to mother and daughter tandem but also to celebrity BFFs.

As the saying goes, "great minds think alike"-- whether it is on the red carpet, matchy hairstyle, or casually hitting the street with coordinated outfits, fans can't help but to notice several A-lister's twinning moments.

From hitmakers like Selena Gomez and Taylor Swift to supermodel best pals Kendall Jenner and Gigi Hadid, we've rundown four best celebrity twinning fashion moments that we've seen on social media and on red carpets.

Ashley Benson and Shay Mitchell

In 2010, the two met on the set of the hit teen drama thriller series "Pretty Little Liars," and the rest is history.

Ashley Benson, known as Benzo and Shay Micthell, as Buttah; hence the duo's nickname "ButtahBenzo," recently took their mini-reunion over TikTok.

The mom-of-one and the blonde beauty danced to the song, "Wow You Can Really Dance."

In the short clip, the "PLL" alums sported a black ensemble featuring dark denim jeans. The only difference is the "You" actress opted for a baggy sweater while the "Spring Breakers" actress wore a black sleeveless top.

Aside from her chart-topping albums and string of controversial relationships, Taylor Swift is known to have a close-knit circle of friends, whom she calls her "squad."

This includes models Martha Hunt and Gigi Hadid as well as Abigail Anderson Lucier and her longtime best pal, Selena Gomez.

There are several occasions that the duo appeared on the red carpet; however, one of the most memorable moments was during the American Music Awards in 2011.

With this, the "Look What You Made Me Do" singer and the former Disney star appeared in complementing shiny, champagne-colored gowns.

The blonde beauty sported a Reem Acra sequined gown while the Rare Beauty owner dazzled in a Giorgio Armani satin dress.
