Justin Bieber is a man of his word.

On the Ellen Degeneres Show back in November, the teen phenom declared he would match a $100,000 commitment by Target to aid impoverished Whitney Elementary School in Las Vegas. On Dec. 16, he made good on that promise, personally delivering a check for $100,000 and performing a mini-private concert (set to kick off at 2 p.m. PST) for students at the school, the vast majority hailing from low income families.

The money, which comes from Bieber’s personal funds and not his philanthropic organization Believe, will go towards providing needy students’ families with food, clothes and money for utility bills. Whitney Elementary also provides assistance to its 610 students, many of them homeless, by providing a food pantry, clothes closet, free haircuts and literacy training on campus.
