Ben Platt in Will & Grace

Platt is recognisable mostly for his role as Benji, in the Hollywood musical hit, Pitch Perfect.

Platt plays Blake, Will’s new (and significantly younger) love interest, in the episode titled “Who’s Your Daddy?”

Blake is of a different generation, a millennial, who makes Will and Jack feel a little out of touch.

Blake’s lack of knowledge about the past also puts things into perspective for Will.

We’re not sure he'll be sticking around for long, but who knows!

Rumour has it there are more exciting guest stars waiting in the wings this season too. 

Will & Grace airs Mondays at 8.30pm on TVNZ, or stream the latest episodes right here.
