Selena Gomez and her ex-boyfriend Justin Bieber have been spending time together at a hotel in Beverly Hills more than once in a week, Hollywood Life reported Thursday. The former popular couple triggered speculations that they are dating again after Gomez was spotted at Bieber’s concert in Los Angeles Wednesday.

Gomez and Bieber are rumored to be spending quality time together at The Montage, according to Hollywood Life.

“Selena and Justin have been spending time together at the hotel more than once in the last week,” a source told the entertainment website. “They’ve been poolside, they’ve had lunch in the dining room, and have had a drink in the bar. While he hasn’t serenaded her on the piano, they have appeared flirty and very touchy-feely.”

The insider went on to tell Hollywood Life that the 23-year-old has been at the hotel “a few times” throughout the week, and that they’ve been “mostly alone” because the two prefer to “spend time with each other than anyone else.”

“They seemed very close, and you could tell there was some obvious sexual chemistry between them,” the insider told the website.

Last month, in an interview to W magazine, Gomez said that she was “so done” with Bieber. “I’m so exhausted,” she told the magazine. “I honestly am so done. I care about his health and well-being. But I can’t do it anymore.”

However, it was recently reported that Gomez and Bieber have been texting each “non-stop” after Gomez reportedly “liked” an intimate throwback photo Bieber shared on Instagam.
