Bieber, 23, and Gomez, 25, seemed happy in the snap, with the two smiling at the camera.

For the outing, Gomez teamed her blue denim jacket with a purple skirt and white sneakers, while Bieber sported an over-sized yellow t-shirt that he paired with black track pants and black sneakers.

Gomez has been spotted on numerous outings with Bieber since breaking up with The Weeknd (whose real name is Abel Tesfaye), who she dated for 10 months. That being said, the two are reportedly said to be trying to keep their rekindled romance "extremely protective".

"It's so fresh and so new and they don't want to do anything that adds any stress," a source told Hollywood Life.

"Since they've reunited, Justin now keeps every promise he makes, and is doing everything he says he is going to do. Selena feels secure in their relationship because he is making it easy for her to trust him completely."

While Gomez seems to trust Bieber, she reportedly had a tough time with The Weeknd, 27, getting close to Bieber's former flame Yovanna Ventura.

"Selena is happy that her ex-boyfriend Abel [Tesfaye] is moving on from their relationship but seeing or hearing about him with other women gets her emotional," a source told Hollywood Life.

The source added, "Selena had a strong bond with Abel and she feels very connected to him despite the fact that he is no longer her boyfriend. Selena will never forget that it was Abel who was there for her, supporting her with love through some scary, challenging health issues."
