Justin Bieber and Selena Gomez have been spotted together numerous times over the last fortnight, but are they a couple again? All signs point to a rekindling of romance between the pop star pair.

Selena Gomez and Justin Bieber
Selena Gomez and Justin Bieber began dating in 2011.

The couple started dating in 2011 and have been in an on-off relationship every since. Things may be back on however as the pair have been frequently sighted together. Two weeks ago a picture of Bieber was posted online and appeared to show him snuggling up to a brunette which reports suggest is Gomez. Whilst last week the pair were spotted attending a bible study class together on Wednesday (18th June), leaving a recording studio on Thursday (19th) and going to the cinema and dinner together on Friday (20th).

On Sunday (22nd) the pair took a trip to the Los Angeles zoo together, chaperoned by Bieber's grandparents. Bieber's grandparents were visiting from Canada so they enjoyed a family day out at the zoo, even posing for pictures with fans and zookeepers. One of Bieber's entourage, Dave Osokow, shared a picture of himself, Bieber, Gomez and a zookeeper on Instagram.

According to a member of the zoo's association, as E! reports, Bieber and Gomez arrived in the afternoon alongside Gomez, his grandparents and two bodyguards. The source said "They arrived around 2 p.m. The occasion was Justin's grandparents were visiting from Toronto and he wanted to do something nice for them. So he brought them and Selena, two bodyguards and his assistant to the L.A. Zoo."

So family days out? Dinner and cinema? Bible study? (Well, we'll let that one slide). But hanging out at recording studios?

It all would point to the pair being firmly back together or at the very least romantically linked. The pair's closeness was commented on by one of the zookeepers who said, "They were very affectionate with each other and they held hands throughout the day." The source added, "The grandparents were equally lovely and everyone was just enjoying having a fun family outing."

Gomez certainly seems to be a positive influence on Bieber who has been dealing with legal difficulties recently. Bieber re-tweeted a picture of himself with a fan, as the girl's father had thanked him for spending time talking to her and posing for a photo. According to E!'s sources, Bieber went out of his way to speak to the fan. The source stated "He went on his own and put his arm around her and it was a very sweet moment and he took some photos with her and her parents."
