BLACKPINK star Lisa has sparked fresh dating speculation after being spotted walking arm-in-arm in London with Thai actor Blue Pongtiwat in September 2026, extending a series of international sightings that have intensified online discussion surrounding the singer’s personal life.
London Sightings and International Encounters Fuel Speculation
The current wave of speculation intensified after a video circulated across online communities showing a woman in a trench coat and hat walking closely with a man in an all-black outfit and sunglasses. The footage, captured on a street in London, shows the pair walking affectionately with their arms linked, prompting widespread online discussion regarding their relationship status.

While neither Lisa nor her representatives have confirmed a romantic connection, the London sighting follows a string of international reports placing the two together over several months. Online accounts previously claimed the pair were seen in Hong Kong and Japan, with a later video surfacing from a trip on August 13, 2026, which a fan held onto out of respect for Lisa’s privacy before publishing it in October. Additional viral posts captured the two at a toy store in London, backstage at the 2026 VMAs in Los Angeles, and dining with Lisa’s family in the Wacharaphon area of Thailand.
Background on Blue Pongtiwat and Previous Rumors
Blue Pongtiwat Tangwancharoen, born in 2000, is a Thai actor, singer, and model who has gained over 2.5 million Instagram followers. Because of his striking appearance, Korean media and online users have nicknamed him the Thai Cha Eun-woo.
He has starred in television dramas including You Are My Heartbeat and the Netflix series Ready, Set, Love.

The two have been friends for several years, with Pongtiwat previously noting that Lisa guided him on dance and served as a mentor. Dating discussions intensified earlier this year after Pongtiwat attended Lisa’s 29th birthday celebration in March 2026, where Lisa shared photos captioned The last of my 20s with my favorite people,
according to coverage of her social media posts.
Shifting Relationships and Industry Pressures on K-Pop Dating
The renewed attention comes against the backdrop of Lisa’s previously high-profile link to Frédéric Arnault, a son of LVMH chairman and CEO Bernard Arnault. That rumored relationship reportedly began in 2022, with the pair spotted at brand events and Italian family vacations, and Lisa seemingly referencing a “French boy” in her song Moonlit Floor (Kiss Me).
However, interactions cooled this year, and Arnault was absent from Lisa’s birthday celebration.

Amid these developments, Lisa addressed the strict confines of her industry in her documentary Always Lalisa.
In K-pop culture, we can’t really date. If you’re seeing someone and you get caught by paparazzi, your popularity drops.

She added that she hid past relationships to protect BLACKPINK’s popularity.

Public Division and Online Backlash
As media coverage and fan recordings have accumulated across multiple countries, public reaction has sharply divided. While many supporters celebrate the sightings, other social media users have directed severe criticism toward Pongtiwat. Following his appearance in backstage clips from the 2026 MTV Video Music Awards, some commentators accused him of leeching off the idol’s fame, leaving disparaging remarks across social platforms. Neither Lisa, Pongtiwat, nor YG Entertainment has released an official statement addressing the dating speculations.
