"Need a lil pick me up? Who you gonna call? Josh [Elliott] and Sam [Champion]!" Roberts tweeted with a photo of her posing between her two friends. "Feel much better now. Blessings." In the photo, Roberts smiles behind a giant sunflower balloon while wearing sweats, a hat and froggy slippers.

"I have been in the hospital 25 days now. My bone marrow transplant took place exactly two weeks ago. The only numbers that matter are my blood counts and they are... GREAT!" Roberts wrote on her "GMA" blog Thursday. "My sister Sally-Ann's stem cells apparently feel right at home in my body -- an answer to so many prayers."

"My doctors and rock star nurses are very pleased with my progress and I could not be more thankful for the excellent care I am receiving," she added. "I have had some extremely painful days and it's still difficult for me to eat because of all the chemo."

And Roberts is also eager to continue her recovery in the comfort of her own home.

"I am hopeful that I MAY be well enough to continue my recovery at home next week and my sisters plan to come back to NYC for that milestone in my journey," she wrote. "I truly FEEL and thank you for your love, prayers and good wishes. And I return it to you tenfold. Light Love Power Presence. XO."
