Justin Bieber and Selena Gomez were spotted spending time with each other at the Montage Hotel in Beverly Hills, California, earlier this week.

Following an unexpected reunion in late October, Bieber and Gomez reconciled their romance. Days ago, Bieber serenaded his on-again, off-again girlfriend at the hotel's piano bar, which he has been caught doing in the past.

“Justin and Selena have met up at the Montage several times in the past few weeks,” an eyewitness revealed to Hollywood Life on Dec. 1. “Every time they look so incredibly happy. A few times, he’s come in to the Garden Bar with her to play the piano while singing to her. They seem to be reliving some of their old, special memories and she looks like she loves it.”

The Montage Hotel's Garden Bar was renovated recently, but according to the insider, Bieber requested that the venue keep their grand old piano at the facility so he could sneak down to the bar late at night and play it. As fans may recall, he did just that in late 2015, when he was seen singing "My Girl" to Gomez as onlookers enjoyed his impromptu performance.

During an interview days ago with Billboard magazine, Gomez opened up about her reunion with Bieber.

“I cherish people who have really impacted my life,” Gomez admitted. “So, maybe before, it could have been forcing something that wasn’t right. But that doesn’t mean caring for someone ever goes away.”

Gomez and Bieber haven't said a whole lot about their reunion, but when it comes to the nature of their relationship, they made it clear that they were in a romantic relationship last month, when they were caught kissing at an ice skating rink in Los Angeles. The kiss came just weeks after Gomez's split from The Weeknd was confirmed. Around the same time, the "Starboy" singer unfollowed Gomez on Instagram.

The Weeknd has also deleted all his past photos of Gomez from his Instagram page and reunited with an ex of his own, Bella Hadid. Weeks ago, as Gomez's outings with Bieber continued, The Weeknd was photographed making his way out of Hadid's home in New York City.

As for a romance between The Weeknd and Hadid, nothing has been confirmed quite yet.
