She recently checked out a treatment center to deal with personal issues, but Demi Lovato has just revealed that she’s already back to work again – and couldn’t be more excited about it.

The 18-year-old took to Twitter yesterday, letting fans know that she’s back in the game by writing, “First day back to working. I can’t wait to share with you guys what I’m doing today. It’s a big day for me. So excited! I love you all!!!”

While Demi didn’t say what she was doing, she did reveal whom she was doing it with. “Wow what a very long but successful day today!! I’m SO blessed to have my friend @Alexavega with me ALL day for support!” she wrote, tweeting a photo of her and the “Spy Kids” star together.

Earlier this month, Lovato teased a new project in a similarly mysterious way, not getting into the specifics of what she was planning next. “I wanted to let you guys know that I’m excited to get back to work. I can’t wait to tell you guys what the future holds. I can’t wait to see you in person. I love you all and I couldn’t have done this without you.”

Joining together for a good cause, Selena Gomez and Jonas Brothers trio Nick, Joe and Kevin took the stage for the Concert for Hope in Los Angeles, California on Sunday evening (March 20).

With Selena and her The Scene bandmates headlining, the slate of performers at the Gibson Amphitheatre at Universal CityWalk was rounded out by Allstar Weekend.

The gig saw all proceeds benefiting lifesaving cancer research at City of Hope, one of the nation’s leading cancer research and treatment centers.

Disney Music Group chairman said of the special concert, “It is gratifying to see a young generation of musical artists come together to support a future free from cancer. We are fortunate to have the commitment of these talented young artists to help City of Hope fulfill its mission of conducting innovative research and saving lives.”

President of Disney Channels Worldwide, Gary Marsh, added, “Some of the most important advances in cancer treatment originated from the work of dedicated City of Hope researchers, including the development of many of the most widely used cancer drugs. It is an honor to support this remarkable institution and its work to advance medicine and pursue research that saves lives around the world.”

She’s sporting a super-thin bod these days, but LeAnn Rimes has a message for anyone judging her petite physique: “I am completely healthy!”

The 28-year-old, who is currently planning her wedding to fiance Eddie Cibrian, spoke out on her Twitter page on Tuesday (March 15) telling, “If people only saw how much I ate.”

Recent photos show the singer, who is always in great shape, looking particularly slim – but she’s firing back responses like, “OVER It is right! I know how healthy I am, so really that’s all that matters.”

Trying even harder to show she’s fit and healthy, LeAnn offered up a glimpse of a meal she ate to her Twitter followers and even jokingly invited fans to see her in the buff, “Maybe it’s time for a nude pic so peeps can see how I look nowhere near what these stupid pics are trying to make me look like, LOL.”
