Chiefs' Mecole Hardman Buys Mom New House, 'My Turn To Take Care Of You!'

"It’s my turn to take care of you now."

AWWWWWWWWWW!!!!

That's new Kansas City Chiefs rookie Mecole Hardman's message to his mom after he surprised her with a new house ... and, yeah, the video is a tear-jerker.

Unclear where the new pad is -- we're assuming somewhere near Arrowhead Stadium so Mama Mecole can watch her son ball with the Chiefs -- but it looks like a sick place regardless.

There's a pool, a brand-new kitchen and plenty of yard space. It's pretty sweet.

"I been dreaming of buying my mama a house since I was 8 and now to finally do it words can’t explain how happy i am," Mecole said of the gift ... "I love you ma x1000000000."

Mecole was a 2nd-round draft pick of the Chiefs and reportedly just inked a 4-year, $5 MILLION deal ... and he said on camera his mom's new house is already fully paid for.
