A report has suggested that Joe Jonas and Ashley Greene can relax now that Demi Lovato is off the scene and tucked away in rehab.

Sources say the couple have been enjoying their time alone together since Demi checked into rehab on Monday.

“With Demi around they had to watch themselves because they didn’t want anything to get even more uncomfortable,” said one insider, reports Showbiz Spy.

“[With her gone] they can now be free and more open with each other, and let their relationship blossom. However, they are happy that she is finally getting the help she needs.”

It was recently suggested that Joe only used Demi for publicity.

“Demi had no idea that Joe was just using her,” an insider apparently said, “and when she found out that the whole relationship was “just for show she had a mental breakdown over everything.”

“She felt everything was a big lie. When Joe and his father told her the truth, she couldn’t deal with anything any more.”

“She totally lost it, and nothing was ever the same after that. She didn’t know who to trust or what was real anymore. In all honesty, she loved Joe, and to find out it was all fake, destroyed her.”

“She immediately started blaming herself after they split, and wanted to change everything. She tried to move on. She started seeing other guys to distract her. But being stuck on tour with Joe and his new girlfriend did her in as we see now… All her feelings just exploded at once.”
