Knick kid’s a champ

She makes Jeremy Lin’s job look easy.

Die-hard Knick fan Gianna Gregoire, 12, just won her nearly two-year battle with brain cancer — and got to meet the team’s breakout star to celebrate the news.

“I got to say hi to Jeremy Lin! I was able to get his autograph,” Gianna told The Post.

She had a quick powwow with the star at Madison Square Garden after he and the rest of the Knicks beat the Dallas Mavericks 104-97 earlier this month.

Sporting a Lin jersey, Gianna also rubbed elbows with center Tyson Chandler, shooting guard Landry Fields, forward Amar’e Stoudemire and Carmelo Anthony’s wife, LaLa.

“They said congratulations, and they told me to keep fighting,” the starry-eyed Gianna recalled.

Hoisting the Bronx native in the air, Fields introduced her to Stoudemire.

“He actually knew who I was!” she said of Amar’e, whom she called “fun.”

“He asked me how I was,” and she told him that she was recently declared cancer free.

“I felt really good inside knowing that I don’t have anything in me.”

Gianna was diagnosed with a germ cell tumor in July 2010 — yet rarely missed a Knick game while undergoing chemotherapy at Columbia University Medical Center.

She caught the Knicks’ attention after her brother, Anthony Donahue, host of Knicks Blog Radio, shared her story on his show.

Last April, the Knicks started the Twitter campaign #winforgianna and held a fund-raiser, at which they auctioned Fields-autographed sneakers and items donated by Brandon Steiner, CEO of Steiner Sports Memorabilia.

Donahue and the Knicks raised several thousand dollars through the silent auction, PayPal donations, T-shirt sales and “Win for Gianna” bracelets.

The Knicks won seven games in a row during the spring 2011 campaign, up until the playoffs.

Donahue, 28, kept his radio listeners updated on his sister’s recovery while Fields and other players tweeted their support.

“She lived in the hospital all of last year,” Donahue said. “I stayed with her every night from July 2010 to late February at Columbia.”

Donahue began taking Gianna to Knick games once she was allowed to leave the hospital.

Gianna lives with her brother and grandmother. Her father left when she was a baby.

“My sister has been through more in 12 years than most people have experienced in their whole life,” Donahue said.

“When she found out she was diagnosed with cancer, she said she was going to beat it.”
