Over the weekend, Lebron James and Nicki Minaj made the dreams of two very deserving fans come true after successful social media campaigns got their attention.

Are Lebron James and Savannah Brinson Having Another Baby?

Lebron James and Nicki Minaj have star power that is out of this world, and in moments like these, it is great to see them use their powers for good. Over the weekend, both celebrities met cancer-stricken fans after social media campaigns vying for each of the girls finally got their attention.

Each star posted pictures to Instagram of their meetings, allowing fans to see that even though they seem to be larger than life, they are never too good to make someone's dream come true.

Nicki Minaj Reunites with Her Young Money Labelmates in New Video Shoot

On Saturday night, Ebony Nettles-Bey warmed up with Lebron James before the Miami Heat played the Milwuakee Bucks. The high school girls basketball player was diagnosed with stage-four Rhabdomyosarcoma cancer, which affects and softens the skin tissue inside of her body.

Before she got sick, she reportedly committed to play at UW-Milwaukee, and has continued to play through her chemo, averaging 4.3 points a game with her Verona High School basketball team.

In February, social media was set ablaze as she and her friends started the hashtag #LeBronMeetEbony. Because of the Heat's strenuous traveling schedule, this weekend was the first time they could make it happen, and after looking at the footage, it was well worth the wait. Ebony walked with James as he entered the court and shook hands with the fans before she started the shoot around.

"I couldn't say anything," Ebony recalled to FOX Sports Wisconsin. "I just started crying, tears of joy."

James was taken aback by Ebony's strength, saying, "What she's going through every single day; the challenges she's facing every single day with the Stage 4 cancer that she has, she's the stronger one out of us two. She's unbelievable."

Also, rapper and actress Nicki Minaj met Miyah, a young friend of NBA superstar John Wall. Three weeks ago, he posted a video to his Instagram asking fans to hashtag #HelpMiyahMeetNicki. The young girl wanted to meet Minaj and to get one of her pink wigs, as she has lost most of her hair to chemotherapy treatments.

On Sunday, Minaj posted a video of the two of them to her Instagram, thanking John Wall for introducing the two of them. Miya, clearly content with her new wig, posed for various pictures as her favorite artist told her, "I'm so happy that you got your pink wig, I think you are beautiful without the pink wig, okay?" She nodded her head with the cutest smile ever and responded, "Okay."

Kudos to Minaj and James for their efforts in supporting their fans and using their star power for good.
