Will Smith isn't the only rapper with a famous wife.

Offset was among those who weighed in on Will's slap heard around the world at last night's Academy Awards.

According to Set, he would react the same way if someone disrespected Cardi B the way Chris Rock did Jada.

"Will Smith the greatest to do it," Offset typed. "I feel you will smack the SH*T out one you n*ggas bout my wife on national tv," Set typed.

Is Will's pugnacious behavior going to start a trend?
