Disney star Demi Lovato is completely back into the swing of things after her life at rehab as she took some personal time to sort out her "emotional and physical" issues. Lovato was spotted at Nokia Theatre L.A. Live enjoying Katy Perry in concert.

After the event, Lovato posted at Twitter to let fans know how great it was.

"So much fun at the Katy Perry concert. She's so talented. Every song is entertaining and live!" Lovato posted according to JustJared.com.

She continued posting on Twitter that she enjoyed a dance party with old friends, new friends and strangers. Her fans are wishing that Demi could finally get back her career for she is such a talented person. But the young performer seems to be taking things one at a time since she took off to regain her physical and emotional strength.

The Disney star, who is known for her singing and acting prowess, starred in such hits as "Camp Rock 1 and 2", had hastily took a leave from her concert tour with fellow artists Jonas Brothers.

Her family denied that it was because of drug abuse, but it was more of some physical and emotional issues that the actress had to deal with during that time.

Reports said it was flurry mix-up of her break-up issues with Joe Jonas and some old issues involving her trauma from being bullied at a young age.

Lovato had a tough childhood, dropping out of school after being bullied. "I had no idea why I was being bullied," Demi told Barbara Walters on the U.S. daytime show "The View".

She wrote more about her experiences in a letter on the PACER's Teens against Bullying website.

"Many people think of bullying as getting beat up in school, but it is so much more than that," she wrote. "For me it was all of the verbal harassment I had to deal with. People say sticks and stones may break your bones but names can never hurt you, but that's not true. Words can hurt. They hurt me. Things were said to me that I still haven't forgotten."

Meantime, Demi's hit Disney show, Sonny with a Chance, was placed on hiatus but Disney backed up their star. "We support Demi's decision to put her health first and we send her our best wishes," a Disney spokesperson said. "She is a talented young woman, and our hearts are with her as she continues to take action to improve her health and bounce back from adversity."
