The pair tried to keep a low profile, as Bieber, 20, was photographed holding the door open for Gomez, 21. The "Boyfriend" singer dressed casually in a white t-shirt and oversized red hat while Gomez looked gorgeous in a white top and kept her brunette locks down.
The twosome were also joined by up-and-coming singer Madison Beer. Back in 2012, Beer, now 15, enjoyed major exposure when Bieber tweeted a link from her YouTube channel. Since getting noticed by the teen sensation, Beer has been working with Bieber's manager, Scooter Braun, and has signed with Island Def Jam.
Gomez appeared content during her late night studio stop by with Bieber, which comes just two weeks after getting served papers. On March 27, the "Come & Get It" entertainer was subpoenaed in L.A. to testify in one of Bieber's lawsuits. Back in 2012, Bieber allegedly assaulted a photographer at the Calabasas Commons while the pair were on a date.
Earlier this month, Bieber also was paid a friendly visit by singer Austin Mahone at a music studio. The stars posed together for a cute snapshot, but an insider told Us that they just "happened to be in the same studio" and there was no collaboration. (As previously reported, Mahone, 18, and Gomez were briefly linked together back in January.)
