Just when we thought we couldn't possibly love Adele any more than we already do, she's proven us wrong once again.

On Tuesday, the "Hello" singer visited a young seriously ill fan in Belfast ahead of one of her world tour performances in the Northern Ireland city.

Rebecca Gibney, a 12-year-old who has cerebral palsy, epilepsy and is unable to walk or talk, was given approximately six months to live last year, but Adele's music has inspired her to keep smiling and defy the doctor's odds, BBC News reports.

Rebecca's mom, Tracy, knew that the 27-year-old pop star was going to be in town for a show and created a petition asking for help in getting her daughter to "meet or FaceTime Adele!"

"She listens to Adele from [the time] she gets up in the morning until her bedtime," the description on the petition read. "All I am asking for is for Adele to FaceTime Rebecca or send her a video message, it would be her dream come true, please, please help for my beautiful sick little daughter."

After a series of tweets, e-mails to Adele's manager, Facebook posts and 363 petition signatures, Tracy and Rebecca's dreams came true -- little Rebecca received a visit from her idol!

Tracy took to Twitter to share highlights from the meet-up, including pics of Adele smiling as she sat right next to Rebecca's bedside.

"I am so blessed and thankful that Adele came to my home today," she wrote.

"I will never forget this day and night my Rebecca and Adele," another tweet read.

In the interview with BBC News, Tracy revealed that Adele's manager called her on Tuesday, informing her that they'd be visiting the Gibney home in an hour.

"It's amazing. I'll never forget it," Tracy explained. "And I do know that when Rebecca passes away she did get her dream come true. It's made me feel like I'm the best mummy in the world which I never felt. Adele told me I was the best mummy in the world, too."
