Last week, Usher's ex-wife Tameka Foster and her family threw a party for her son Naviyd Raymond's 4th birthday. She invited Santa Claus, Scooby Doo, and basically her whole family. Unfortunately, Usher didn't make the party, and proceeded to subtweet Tameka on Twitter.

"I said I'd never trust a b***h my best friend. :-) OK ok ok, i'm done with saying b***h...just had to say b***h one more time. 34," tweeted Usher with a picture attached of him and his dog. But, Usher did make it up to little Navi, throwing him a half Scooby Doo, half rock climbing party as well. Check out the pictures from Navi's party above.
