There's happiness once again in singer Justin Bieber and Selena Gomez's love paradise, if reports are anything to go by.

The on-again, off-again couple first started dating in 2010 and most recently split last month. However, they are said to have appeared "very close" after arriving separately for a Bible study class at a church here earlier this week.

"Justin looked really comfortable with Selena as he still thinks their bond is unbreakable and knows that Selena will always love him," a source told Britain's Daily Mirror newspaper.

"The pair sat next to each other while partaking in Bible study and seemed very close. They then left together in Bieber's car," the source added.

The "Baby" singer also shared a blurry photograph of the "Come and Get It" hitmaker, 22, kissing his cheek as he holds her in his arms on his Instagram profile, captioning it: "Right now everything else is a blur."

However, he deleted it soon after.
