'Waitress' Stars Katharine McPhee & Erich Bergen Attend the Tony Awards 2018!

Katharine McPhee looks beautiful on the red carpet at the 2018 Tony Awards held at Radio City Music Hall on Sunday (June 10) in New York City.

The 34-year-old entertainer was joined at the event by fashion designer Zac Posen and her Waitress co-star Erich Bergen.

Katharine, who will present during the awards show, is currently on Broadway in the Waitress and she has extended her run through August!

“Catch me on stage tonight presenting at the #TonyAwards2018! If you’ll be tuning in, like this post because @grantthorntonusa is donating to two amazing charities in their #SupportingCast campaign, @thewing & @broadwayleague, both of which support the arts and celebrate all things Broadway!! #ThisIsBroadway,” Kat captioned the below Instagram post.

FYI: Katharine is wearing a Zac Posen dress.
