The Summer I Turned Pretty star Lola Tung was seen partying at a nightclub in Clapham, London.
The 22-year-old, who plays Belly Conklin in the Amazon Prime series, hung out at Infernos in south-west London.
Tung made a secret stop in London before heading to the TSITIP series three finale screening in Paris on Wednesday night.
An astonished reveller shared a TikTok with Tung on the dance floor with the jokey caption: “The summer Belly swapped the Fisher brothers for the finance bros at Infernos.”
The clip showed the actress wearing tinted glasses and laughing as the TikToker said she was “Team Conrad for life,” referring to the love triangle between Belly and brothers Jeremiah and Conrad Fisher.
Tung burst out laughing and pulled a mock-grimace, protesting, “I can’t say anything!” in a bid to avoid spilling any spoilers.
The rising star isn’t the only celebrity who has partied at Infernos, with Barbie actress Margot Robbie previously admitting to going on nights out at the haunt while living in London with her friends and now-husband Tom Ackerley.
“Everyone is wasted and so sweaty,” the star, then 25, told the Sunday Times in 2016.
“Everyone looks a mess. By the time I make it to Infernos, I look so revolting that nobody’s going to look twice.”
The TSITP series finale - which saw Belly choose Conrad over Jeremiah - drew 25 million viewers globally in its first week, highlighting the show’s mix of first love, heartbreak, and coming-of-age summers.
On Wednesday it was revealed the saga will be wrapped up in a feature film. Jenny Han, the author behind the beloved book trilogy, will co-write the movie with Sarah Kucserka.
The film promises to bring back the series’ main cast: Tung, Christopher Briney, 26, and Gavin Casalegno, 27.
Amazon has hinted that the film will continue immediately after the dramatic events of the third series, with new locations and storylines that didn’t fit into the television format.
Speaking at the Paris red carpet for the series finale, Han said: “There is another big milestone left in Belly’s journey, and I thought only a movie could give it its proper due.”
