They are fully back on! Selena Gomez and Justin Bieber spent the entire weekend together, and have been "declaring their love for one another." Do you think Jelena will be together forever?

"Justin and Selena spent the entire weekend together and it was filled with lots of 'I love you' talk on both ends," a source told TMZ.

The site also notes the two have been referring to each other as "boyfriend" and "girlfriend" again.

We told you last week the two reunited at bible study at City Church in Los Angeles. They enjoyed low-key activities this weekend like hiking and hanging out at home. How sweet!

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

"Justin looked really comfortable with Selena as he still thinks their bond is unbreakable and knows that Selena will always love him."

The "Boyfriend" singer added fuel to the fire by tweeting, "God is good."

Jelena have been on and off since 2010.

Bieber recently handled a string of legal troubles, while Gomez made career and personal changes.

Both participated in the ALS Ice Bucket Challenge over the weekend after being nominated by fellow celeb pals.

We are sure not everyone is thrilled to see the couple back on. Demi Lovato allegedly had it with the drama, and explained on "Watch What Happens Live" why she unfollowed the star on Twitter.

The former Disney star played "Plead the Fifth" with host Andy Cohen.

"You recently unfollowed your BFF Selena Gomez on Twitter. So much speculation about this. Can you tell us why?" Cohen asked the star.

"I Plead the Sixth...if that's in the game," Lovato replied.

He continued to pry, asking if fans were "reading too much" into the situation.

"I think it's just one of those things where people changed and people grow apart," the "Neon Lights" songstress explained.
