Sally-Ann Roberts, who gave Robin her life-saving bone marrow donation, is retiring after 40 years in New Orleans News.

There's a lot of love between Robin Roberts and her sister, Sally-Ann.

Robin took a moment on Wednesday's Good Morning America to wish her sister well as she retires from anchoring New Orleans' WWL-TV news after 40 years in the business.

"You know how much I love my family and my sister. She is an icon in New Orleans and she made an announcement that the family has been prepared for. She made the announcement that she will be retiring in February," Robin shared on the show. 

"She’s been on the air for 40 years there. She’s the reason I’m doing what I’m doing," she tearfully added. "These are tears of joy. She has done so much for the community. I really am happy! She’s so excited."

Sally-Ann was also Robin's bone marrow donor when she had to step away from GMA to undergo life-saving treatment.

"The reason I am here doing GMA and alive is because she was my bone marrow donor," Roberts explained.

Clearly, the bond between the two sisters runs deep.
