FOX TCA All-Stars 2018: Malcolm-Jamal Warner and Mark-Paul Gosselaar unexpectedly steal the show

It's official: Mark-Paul Gosselaar and Malcolm Jamal-Warner are still the coolest guys in school.

Both men made appearances Thursday at the Television Critics Association summer press tour, and at 44 (Gosselaar) and 47 (Warner) the two proved that heartthrob status is eternal.

Gosselaar, who played Zack Morris on "Saved by the Bell" and now stars on FOX's sci-fi drama "The Passage," played it cool in a deep blue suit over a white tee. Warner, best known as Theo Huxtable from "The Cosby Show" and now appearing on FOX's "The Resident," mixed things up a bit in a gray vest over a white shirt.

Also looking glam at the event were Jenny McCarthy and Jennifer Love Hewitt, both of whom looked lovely in figure-flattering dresses.

Hewitt spoke excitedly about her new role on "9-1-1," telling ET, "It’s a beautiful show. I mean, you can’t get through an episode without crying or feeling something incredibly intense."
