ATLANTA -- Teenage friendships can be fickle and fleeting, but not Leah and Kera's.
"I was outside one day and she was too," said Kera.
"Yeah in the garden, she came up to me," Leah chimed in.
"And I was wondering what she had, and she was wondering the same thing about me," Kera finished the thought.
Kera has Ewing Sarcoma, a bone cancer. Leah has leukemia. Both spend far too much time in the hospital, but they have found each other and in typical teenage fashion, they share their love of shopping, albeit modified.
"We both like to shop," they look at each other and laugh.
"We've actually ordered some of the same wigs off a website and talked about different places to get hats and stuff."
But last month, Leah met someone else. Dunwoody native Ryan Seacrest popped into her room at Children's Healthcare of Atlanta and helped her with an important decision.
"I actually got picked for homecoming, and I had some pictures of my dress choices, and he helped me pick out the one to wear," Leah said.
She wore the one he picked.
Seacrest showed up for another event at Children's on Friday and remembered helping Leah.
"Yes it was a big decision," he said. "I'd seen a lot of dresses in the past, and we picked that one and it worked out perfectly for her."
Seacrest is back to unveil "The Voice" -- Children's version of a broadcast newsroom, brought to fruition with the help of Seacrest's foundation.
"I hope it brings a spirit and energy, something special for the kids who have to be here for a little while or a long time," Seacrest told 11Alive News.
Seacrest's visit was broadcast to patients in all three hospitals, and patients will be able to do broadcasts for each other.
Wearing a stylish outfit picked out with help of several girlfriends and her sister, Leah is Seacrest's first interview to be broadcast. She tells him why the voice will help with sick kids.
"I know. Sometimes you don't feel good enough to come out of your room."
Seacrest spins some music, an immediate hit in a treatment room where patients sway back and forth to the beat.
Many young patients had a rare encounter with a Hollywood star, but the permanent impact of this gift will give children fighting for their health..a voice.
