The "Hello" hitmaker took time out to drop by Rebecca Gibney's house before her second concert in Belfast, reported Aceshowbiz.
Following online campaigns by Rebecca's mother, the singer made a visit to young girl's home and sat by her bed with the family.
The star offered the family tickets to her second show on Tuesday at the Short Strand area.
Before Adele's first show, Rebecca's mom, Tracy, launched a petition on Change.Org to get the "Hello" hitmaker to meet her "very sick daughter who's cerbal paulsy, epilepsy, can't walk or talk and is tube fed, she has recently became bed bound."

She also tweeted, "I am going to see Adele tomorrow night can anybody help me to get to meet her back stage and tell her all about wee Rebecca thanks" and several other similar pleas along with pictures of her daughter.
According to Tracy, she hadn't got any reply from Adele's team so she was shocked to find the star show up on her doorstep.
