Justin Bieber and Selena Gomez are no longer trying to keep their relationship on the down low. The pop singers were spotted entering a recording studio in Miami on Tuesday, just a month after the duo reconnected over a weekend in Texas. Gomez arrived at the The Hit Factory in a long black skirt, combat boots and a white crop top. Bieber also kept it casual, sporting black a white shorts and a large white tee. The couple was also joined by mutual friend Madison Beer, who shared a picture of the gathering on her Instagram account. Sources tell Hollywood Life that a duet featuring Bieber and Gomez was "not out of the realm of possibility." However, a source close to the "Come and Get It" singer begs to differ. "They are keeping their music separate and their relationship the main focus to work on," the insider said.
