LONDON – Justin Bieber and Selena Gomez are like "two lovesick school kids".

The Never Say Never hitmaker and the Wolves singer rekindled their romance late last year, just weeks after she split from her boyfriend The Weeknd and friends say they are more in love than ever.

A source told The Blast: "They are like two lovesick school kids who can't get enough of each other."

Meanwhile, the couple are seeking guidance from their Hillsong pastor Carl Lentz about their relationship.

A source previously said: "They don't want to repeat the same patterns as before. They've clearly had issues in the past, so they're receiving some guidance from Carl. They love each other [and] truly do want the best for each other."

And Justin, 23, is said to be feeling "lucky" that he has rekindled his romance with the 25-year-old Bad Liar hitmaker.

An insider shared: "Justin wants to be a better man because he doesn't want to screw things up with Selena. He knows he's lucky to have this second chance and he's not taking it for granted. And the truth is, this 'transformation' hasn't been all that difficult for him because he wants it.

"It's true that you can't change someone unless they want it, and he wants it now. He knows what's at stake. He would way rather spend a quiet night in with Selena than go get wasted and hook up with random girls. That lifestyle just doesn't appeal to him anymore. Selena is 100 percent the reason Justin turned his life around. She's the one that got him involved with church and that opened up a whole new group of friends to him too."
