They can be each other’s company — all the time! Now that Justin Bieber and Selena Gomez are back on and planning to marry, as Life & Style recently reported, they’re not wasting any time.

“They’re already hunting for a home so they can move in together,” an insider exclusively reveals. “It was Selena’s idea, and Justin is all for it. He’s already looking at homes in the Calabasas [CA] area. They just can’t wait to start their life together.” After dating on and off for nearly four years before splitting in 2014, Jelena has been inseparable lately, stepping out for a brunch date in NYC, biking around LA, and attending church together.

As solid as they seem, Selena’s family hasn’t forgotten how she fell to pieces after past breakups. And they worry about her emotional and physical health now that the singer, who suffers from the autoimmune disease lupus and received a kidney transplant over the summer, is back with Justin. “They want Selena to remain healthy,” says a second source, “and feel this could be the biggest mistake of her life.”

Still, Justin, 23, and Selena, 25, are determined to jump into their new life together. “They’ve both grown up so much,” insists the insider. “Being apart was crucial for them to move on and to realize they were meant to be together. Buying a home to live in as a couple will seal the deal.”
