This may have been the best New Year’s yet for Robin Roberts.
Exactly 100 days after successfully undergoing a bone marrow transplant, the Good Morning America host was reunited with her beloved dog, KJ, just days before ringing in 2013.
“Look who made it back for my 100 day celebration,” she Tweeted on Dec. 29, with a photo of herself and KJ in a cuddly embrace. “We just keep staring at each [other] … can’t believe she’s finally home.”
Roberts, who had the transplant Sept. 20, suffers from a rare blood disorder called myelodysplastic syndrome. The 100-day mark is a criticial milestone in her long recovery and she celebrated it on Twitter earlier that day.
“Every morning I mark the day post my bone marrow transplant. Today I reached a major milestone … Day 100! Blessings..XO,” she wrote.
In November, Roberts said that with each day comes a newfound strength.
“It’s a journey that kind of zigzags, and there are complications and things like that, but I feel good. I feel stronger every day,” she told her sister and donor, Sally-Ann Roberts, in an interview.
With KJ now by her side, her support system is even larger.
“Couldn’t resist sharing one more photo KJ already feeling right at home,” she wrote, with a photo of the dog snoozing on her leg. “So happy to have the lil girlback.”
