The 19-year-old actress downplayed her romance with the 34-year-old reality star Friday on Twitter after Disick was spotted kissing ex-girlfriend Chloe Bartoli in Cannes.
"Hahahah I'm not talking to Scott or anyone else," she wrote in response to a fan who tweeted, "Waiting for @bellathorne to tweet that she's not talking to Scott and that she's actually with someone else."
Thorne and Disick were first linked last week following a dinner date in Los Angeles. They flew out to France together Monday. The pair were spotted kissing and cuddling by the pool at Disick's rented villa Wednesday.
"They spent all day laying out and flirting with one another. They kissed several times and at one point Bella laid on top of Scott and ran her hands through his hair," a source told E! News at the time.
Disick was photographed getting close to Bartoli on Thursday. Thorne appeared to call it quits in a tweet the same day.
"Yo this #cannes fancy life isn't for me," she wrote.
Disick's flings with Thorne and Bartoli follow news his ex-partner, Kourtney Kardashian, is dating Younes Bendjima. Disick and Kardashian split in 2015 after Disick was spotted cozying up to Bartoli in Monte Carlo.
