A Chatham girl who survived a brain tumour had a dream come true Wednesday night when she met Lady Gaga.

Ten-year-old Avery Fournier spent 15 minutes with the entertainer following her Toronto concert.

For a 10-year-old who's no stranger to fighting battles, the encounter was inspirational.

“She’s a really good person. She’s not just about the fame, she cares too, about…the fans.”

And it was also a “shocking” encounter as Avery’s mother didn’t tell her about the surprise beforehand. “She was keeping it a secret from me.”

Avery says Lady Gaga told her to stand up for herself and be herself.

Avery is an inspiration herself, having battled a brain tumour that left her legally blind. She can’t see more than 16 inches away.

The backstage meeting happened after her mother reached out to The Toronto Star…who managed to get word to Lady Gaga's staff. 

“It was exciting for me because I’ve been pushing for this for so long,” says Avery’s mother Chris.

She says it was touching to see the star get right up close to her daughter’s face for about 30 seconds and rub noses.

Avery also received an autographed concert book from Lady Gaga.

The tickets to the concert were given to her by an anonymous donor.
