Blake Lively reunited with Gossip Girl co-star Dorota in a Betty Booze ad.

XOXO: Sweet Reunion of the Upper East Side

Blake Lively gave Gossip Girl fans the reunion they’ve been waiting for.

The actress, 37, brought back a beloved character from her CW days in a fun ad for the Betty Booze brand—none other than Dorota herself, played by Zuzanna Szadkowski.

Sipping Tea with Nostalgia

In this playful new campaign, Lively and Szadkowski meet on a park bench to catch up and literally “spill the tea”—that is, Betty Booze’s new Vodka Iced Tea flavors.

The commercial begins with a Gossip Girl-style sneaky photo snap, after which the two remove their dark sunglasses for their secret meeting.

“I have tea,” Szadkowski announces with a revealing look.

“Good tea?” Lively asks.

“Oh, best tea,” Szadkowski replies, revealing new canned cocktails.

Inside Jokes for Faithful Fans

The commercial is filled with hints about their shared television past.

When Lively jokes that Szadkowski is “doing a different sound,” poking fun at Dorota’s iconic Polish accent, Szadkowski immediately replies, “Oh, allergies.”

The ad ends with Szadkowski returning to character, with the accent: “Oh, Miss Betty, you’re going to get us in trouble.”

New Flavors Worth Gossiping About

The reunion celebrates the launch of two new Betty Booze Vodka Iced Tea flavors: Meyer lemonade and passion fruit.

Szadkowski describes them as “balanced, crisp, nothing artificial,” after which Lively adds with perfect timing, “which is hard to find in these areas.”

Lively playfully commanded fans in the video’s caption, “Go. Sip, girl,” a clever nod to the show’s title.

Betty Empire Expands

This latest addition expands Lively’s growing beverage empire.

She launched Betty Buzz sparkling mixers in 2021, followed by Betty Booze’s tequila and bourbon canned cocktails in 2023.

“I’m from a Southern family, so iced tea, especially in the summer, is a staple,” Lively told PEOPLE earlier this month.

“Sweet tea, passionfruit tea, tea with fresh lemonade … it all feels like relaxation and peaceful times.”

This Is Not Their First Reunion

Both actresses have occasionally reconnected with their Gossip Girl families since the show ended in 2012.

Szadkowski has previously reunited with several cast members in 2022, including Chace Crawford, Jessica Szohr, and Ed Westwick.

For fans of the iconic series, seeing Serena and Dorota together again—even if it’s just for a commercial—brings back all the Upper East Side feelings.

And this time, there’s a proper drink to toast to.
