Tyrel Jackson Williams is an actor who stars as Leo Dooley on the Disney Channel series Lab Rats. Because of that, he appeared in a deleted scene from Muppets Most Wanted, appearing as a wedding guest with fellow Disney Channel stars Bridgit Mendler, Debby Ryan, and Jake Short in a demonstration of "Disney synergy."
On Everybody Hates Chris (with brother Tyler as the younger Chris Rock), Williams appeared a few times as a still younger Chris Rock in flashbacks. He has also appeared in Modern Family, Pair of Kings, and Community (twice as Shirley's son Jordan).
