Bowen Yang claims that the cast of “Saturday Night Live” had no idea about Taylor Swift’s and Travis Kelce’s unexpected cameos on Saturday’s season premiere — but he was even more shocked by the couple’s height.

The “Fire Island” actor, 32, gave a play-by-play of realizing the “Shake It Off” singer, 33, and two-time Super Bowl champ, 34, came to 30 Rock to appear on “SNL” last weekend.

“I walk outside to go to my makeup chair. I see two people talking to two tall people — tallest people in the world,” Yang dramatically reenacted Wednesday on his “Las Culturistas” podcast, which he hosts with Matt Rogers, 33.

“By the way, it’s one thing to see them individually in a space. But it’s [a] pure force multiplier [seeing them together],” he said of the couple’s height.

“I see them together, I go, ‘I am in the redwood forest,’” Yang recalled.

Kelce appeared at the tail end of the show’s “Fox NFL Sunday” sketch, which spoofed commentators trying their best not to bring up Swift.

Meanwhile, the “Karma” songstress was on hand to announce musical guest Ice Spice’s second performance of the night.

The Bronx rapper performed her hit “In Ha Mood” earlier in the show before she hit the stage for a performance of “Pretty Girl” with collaborator Rema after Swift’s introduction.

The Post has contacted reps for Yang, Swift and Kelce for comment.

Swift and Kelce have yet to officially announce they’re dating, but Swift’s signature red lipstick all over Kelce’s lips this weekend seemingly tells fans everything they need to know.
