Is BLACKPINK Lisa dating Blue? Thai actor linked to K-pop star amid Frédéric Arnault split rumours

BLACKPINK star Lisa has been linked to Thai actor Pongtiwat Tangwancharoen, known as Blue, following renewed speculation about her relationship with French businessman Frédéric Arnault.

The K-pop singer and Arnault have been romantically linked since 2023, when they were spotted together in Paris.

Their appearances during trips abroad fuelled dating rumours, although neither has publicly confirmed their relationship. There has also been no official announcement of a split.

The latest speculation centres on alleged sightings of Lisa and Blue in London.

Social media posts reportedly showed two people believed to be the pair at a toy shop and walking together on a street. In one clip, the woman believed to be Lisa appeared to hold the man's arm.

However, the identities of those featured in the footage and the nature of their relationship have not been independently confirmed. Neither Lisa nor Blue has publicly acknowledged a romantic connection.

The alleged sightings have prompted mixed reactions online, with some social media users accusing Blue of "clout chasing" through his reported association with the BLACKPINK singer.

Others have defended Lisa, arguing that her personal life should not invite criticism.

Lisa and Arnault were first linked after being seen together in Paris in 2023. Their relationship status remains unconfirmed, despite ongoing speculation.

Meanwhile, Lisa continues to balance her solo promotions and professional projects.
