Actor Chuck Norris sent a very special message to a four-year-old Florida girl in a tough battle with a rare bone disease. In the video message, Norris called the young girl, Jenna, his “hero.”

Jenna had expressed how much she enjoyed the Chuck Norris cartoon “Chuck Norris: Karate Kommandos” in an interview with WJHG. After hearing this, Norris sent a video message to the young fan which was waiting for her when she got home on Tuesday.

“Hi Jenna, I saw you on television and I want to thank you for allowing me to be your hero,” said Norris in the video. “But I gotta tell you a secret. After watching you on television and seeing the battle you are facing, you are my hero.”

Norris promised to meet Jenna and her family when he returned from a trip overseas. Jenna said she will be practicing her karate moves for when they meet. “I’m going to count down the days to see him,” she told WJHG.

Norris isn’t the only celebrity to use his stature for good or to help someone’s dreams come true. There are plenty of other celebs that make us smile with their good deeds.

Wrestler and actor John Cena, who crossed the milestone of 500 wishes granted through Make A Wish in 2015, made one young fan’s dreams become a reality when he stopped in Columbus, Ohio, in July of last year for a WWE event.

Isaac, a pediatric cancer survivor, was attending the wrestling event with a Make A Wish t-shirt and Never Give Up headband when Cena spotted him in the crowd and decided to bring him inside the ring. “I always preach the motto ‘Never Give Up,’ it’s one thing to talk about it, but it’s another thing to do it,” said Cena with Isaac smiling next to him.

“Ladies and gentlemen, you have been a wonderful crowd tonight, but I wanted to make Isaac’s Independence Day by giving him a moment of what it’s like to be a WWE superstar,” Cena said as the crowd cheered for Isaac.

One Direction band member Harry Styles agreed to record a video message for a four-old-fan dying of cancer after the father posted a viral, black and white photo of the girl to Facebook. Father Andy Whelan posted on Facebook after his daughter, Jessica, received a personal phone call from 22-year-old Styles, “Well that was a surreal telephone call … An unknown number I answered for it to only be HARRY STYLES ringing from USA!!! He wants to do a FaceTime or video recording for Jessica! The way she is at the moment I have told him that she would benefit more from a recording which he has said he will do for her and email to us!”

Jessica Whelan passed away at the end of November — but was given the chance to talk to her favorite singer first.

While not a single celebrity, Disney granted the wish of “Star Wars” fan Neil Hanvey. After being told he only had six to eight months to live, Hanvey had one final request: He wanted to see “Rogue One: A Star Wars Story.”

The staff at Hanvey’s hospital, St. Michael’s Hospice, launched a social media campaign and got #RogueOneWish trending. After “Star Wars” actor Mark Hamill jumped onboard the campaign, Hanvey was allowed to be screened the film in August of last year.

St. Michael’s Hospice said in a statement: “On behalf of Neil Hanvey, his wife Andrea and all his family, we want to thank everyone who supported the #RogueOneWish campaign. The director of ‘Rogue One,’ Gareth Edwards did all he could to make Saturday a very special day for Neil. Neil, his family and everyone at St Michael’s Hospice would like to say thank you to Disney, Lucasfilm and especially Gareth Edwards.”
